The ESQT-142-02-S-D-309 is an insulated rectangular connector which belongs to the family of rectangular connectors, including headers, receptacle, and female socket. This type of connector is mostly used in areas such as telecommunications, medical, aviation, industrial applications, and more.

Rectangular connectors have a better integrity and higher vibration resistance. They are usually faster and easier to assemble and disassemble, which makes them ideal for applications that require frequent connections and disconnections. Meanwhile, compared to circular connectors, their lighter weight allows them to fit where size is limited. In addition, rectangular connectors can also help to block out more EMI than those of the round type.

The ESQT-142-02-S-D-309 is a low-cost rectangular connector with a 2.54 mm centerline spacing and a 9.53mm total depth. It is designed for more rugged applications since its shell is made of DChrome alloy steel resulting in more heat resistance and higher vibration resistance. The connector also features two sets of springs and the insulation cover is made of PBT/ 30% GR polyester.

In terms of the working principle, the ESQT-142-02-S-D-309 has a host of contact pins, which provide a reliable electrical connection when mated. The pins are contained in insulator housing that securely holds them in place. This means that the pins cannot vibrate out of the contact regardless of how fast the connection is made or broken. The pins also have a small knob that protrudes outside of the body, allowing the pins to also be soldered into application boards. This enables a more secure connection.

The ESQT-142-02-S-D-309 is designed to provide a reliable connection, withstanding temperatures up to 105°C making it suitable for a wide range of applications in areas with high thermal loads. The connector has a rated current of 3.0A and a rated voltage of 250V AC. It also has a high level of insulation resistance, and its contact resistance is low. These features help to ensure a strong and reliable connection.

In conclusion, the ESQT-142-02-S-D-309 is an insulated rectangular connector that belongs to the family of rectangular connectors. It is perfect for applications with fast connections and disconnections, and it can stand up to high thermal loads. It is lightweight yet rugged, and it can provide a reliable electrical connection with its contact pins, all with a low contact resistance and high insulation resistance.
