Connectors.
The core elements of the TE Connectivity range are, of course, connectors. There are hundreds of items available, serving a wide range of purposes: from data and signal transmission and power supply to typical industrial applications. The complete range of TE Connectivity connectors in our catalog is available at the following link. It's worth noting that the vast majority of items are shipped directly from our warehouses, minimizing delivery times to our customers.

Industrial Rectangular HDC Connectors.
Rectangular connectors designed for harsh operating conditions, i.e., HDC connectors, are industry standards. Their modular structure and high mechanical strength facilitate their use in machine parks and equipment exposed to extreme environmental factors (temperature, dust, vibration, etc.). TE Connectivity connectors in this category are made of high-quality aluminum (housing material), and their contacts in most models are silver-plated, making the entire structure corrosion-resistant. This ensures a low failure rate and, in the long run, reduces downtime and service costs. Most models are rated for 10A and 16A currents (although 35A models are available). A single housing can accommodate an insert with 4 to 72 pins (and a separate conductor/shield).



Male HDC connector for 16A currents.
The connectors, available in male and female versions, feature various locking systems: single or double latches, or screw mounting. TME's offering includes not only housings and connectors but also other accessories for this TE Connectivity product family, such as end caps, frames, cable glands, etc.
 


THT mounting plugs are available in bulk packs.
Another manufacturer's solution focuses on board-to-board and board-to-cable (ribbon) connections. This Micro-MaTch series is manufactured with a 1.27 mm pitch, allowing for a compact design and saving space dedicated to connections between device components. The connectors are designed for cables with a diameter of approximately 0.08–0.09 mm² (or 28 AWG). The contacts are manufactured using a special system that employs spring elements to absorb vibrations and ensure good adhesion of the polymer housings, protecting the joints from corrosive factors, especially moisture. The connectors themselves are made of aluminum. Thanks to their design and availability in rolls, the connectors can be assembled both manually and in automated processes.
The catalog includes Micro-MaTch connectors in vertical, angled, and straight variants. They can be mounted on PCBs using through-hole (THT) or surface mount (SMT) technology, depending on the model. Plugs designed to secure flat cables are embedded using in-line die (IDD) technology, meaning they pierce the cable insulation. TE Connectivity designed this product series with industrial, consumer, and ICT applications in mind.

MATE-N-LOK Universal Signal Connectors
from TE Connectivity offer connections found in many controllers, both industrial and consumer (appliances), wherever the electronic system controls relatively high loads. Their function is to connect wires to PCB circuits and they are rated for up to 600V AC and 19A. The series supports connections of 2 to 15 wires. The connectors are designed with a 0.25-inch (6.35 mm) pitch, allowing for safe spacing between circuit paths. MATE-N-LOK connectors are available in male and female versions, mounted to a PCB using through-hole technology (THT) and to wires via crimping. Tin-plated contacts (gold-plated versions available) are suitable for wires with cross-sections from 0.5 mm² to 2 mm², approximately 20-14 AWG.



MATE-N-LOK connectors are equipped with side-mounting clips.

Passive Components
In addition to the extensive portfolio of connectors that forms the backbone of the TE Connectivity range, the brand offers many other electronic components designed for industrial, military, civilian, and consumer applications. Among these, we can distinguish passive components. Two specific product groups are discussed below; however, we highly recommend that you view TE Connectivity's complete selection of passive components in our catalog.

HOLCO Series Audio Resistors.



HOLCO resistors are covered with a durable epoxy resin coating. The HOLCO series includes precision metal resistors that are resistant to thermal influences—the maximum resistance change due to temperature is 100 ppm/°C, although many models have a resistance of 5 ppm/°C. These resistors are available only in THT versions, with values ​​ranging from 3.3 Ω to 3.3 MΩ. Their primary application is in audio amplifier and converter circuits, thanks to their tight tolerance (1%) and high-temperature resistance (up to 70°C); however, they also perform well in demanding industrial and military systems. The models available in the TME catalog belong to the H4P group and are 1-watt resistors. 

Mains Filters.
TE Connectivity's mains filters are grouped by the manufacturer under the name Corcom. They are compact devices that filter the power supply (250V, 440V, or 480V AC) against electromagnetic and radio interference (RFI), which can be a serious problem, for example, near transmission/reception stations, TV transmitters, etc. These devices are therefore suitable for a wide range of applications. Depending on the model, they can handle loads from 1A to 30A, thus meeting the requirements of many industrial projects. TE Connectivity filters connect to the mains using pre-installed cables, 6.3 mm connectors, or an IEC socket (which is useful, for example, when installing them on a mobile device). The primary purpose of these products is to work with switched-mode power supplies, where they serve a dual function: ensuring good power quality for the unit and protecting the installation from power supply disturbances.

Automation:
Since most TE Connectivity products are used in machine parks, production lines, smart buildings, etc., it was a natural move for the company to enter the automation components market. Many of the supplier's products can be found in the TME catalog, primarily relays and their accessories (plugs, clamps, etc.). You can view the full range of these items by clicking the link below.

TE Connectivity Electromagnetic Relays:
TE Connectivity offers a wide selection of relays. Most of them are miniature electromagnetic components. These are the RT series..., each with its own unique characteristics. The advantages of this range include good thermal resistance; most models tolerate temperatures ranging from -40°C to 70°C, while variants with an upper limit of 85°C and even 105°C are available.
 


The RT2 relay has parameters typical of the household appliance and small automation segment.
The RT1 series includes simple relays equipped with one or two poles (SPST and SPDT configurations). The relatively high maximum current rating of these elements allows them to be used to control inductive loads in the field of home and industrial automation, such as supplying power to heaters, motors that operate automatic doors, curtains, etc. The installer can choose products with coil voltages from 3V to 24V DC, as well as 24V, 115V, or 230V AC. The components are designed for through-hole (THT) mounting, meaning they are designed to be mounted on a PCB (3.5mm and 5mm pitch). Most TE Connectivity relays, including the RT series, are designed for mass mounting, reflow soldering, or THR.
The same applies to the RT2 series. However, this group supports lower currents (8A) and only has outputs with a 5mm pitch. The components are designed in accordance with the international standard IEC60335 concerning safety standards for electrical appliances. The RT2 series is the only one in the TE Connectivity product range that includes dual relays, meaning they have both DPDT and DPST contact configurations, including bistable variants, which are often used in lighting control.
The less numerous RT series include RTH and RTS. RTH is a group of components distinguished by their resistance to temperatures up to 105°C. They can withstand currents up to 16A. These are standard parameters, typical of domestic electrical installations and kitchen appliances. The RTH series is designed for installation in the control circuits of ovens, induction hobs, etc. Components bearing the RTX designation are bistable components adapted to the requirements of fluorescent lamp ballasts. Their overcurrent rating is 320A, and the maximum switching voltage is 250V AC. These components will prove their worth in lighting automation applications; they can work with motion sensors, switches, and also as parts of more complex controllers (time relays, etc.).

Miniature Pressure Sensor
Finally, we suggest you familiarize yourself with an item that perhaps not everyone would expect from TE Connectivity. This brand is increasingly developing its offerings in the field of industrial sensors (and beyond). The MS5803-02BA01 model is a pressure sensor – it offers absolute measurement in the range of 10 to 2000 bar. The sensor is characterized by its small dimensions (6.4 mm x 6.2 mm) and is designed for surface mounting on digital circuits, as it offers I2C/SPI outputs. The sensor is hermetically sealed and does not require the use of external components (it has a built-in oscillator), allowing its use, among other things, in devices operating outdoors.
