SQT-139-02-F-5 is a type of rectangular connector. It is a header and receptacle, containing both a female socket and a double row of pins that are used for mating. It is typically used for compact, space saving connectors in tight spaces, with a low profile design for applications requiring mechanical stability as well as electrical connectivity. This type of connector has a variety of applications and market segments, such as consumer electronics, automotive, industrial automation, medical equipment, and telecom.

SQT-139-02-F-5 connectors consist of a plastic housing containing pins and a female socket, usually with a latch and a height of 8.5mm or less. They’re typically used in applications where a “blocking off” feature - where the pins are connected to a male counterpart, rather than being freely exposed - is a requirement. This makes them well suited to a number of customised applications, such as those in the telecom sector.The number of contacts on SQT-139-02-F-5 range from 2 to 20 and the pitches between contacts range from 0.2mm to 1.27mm. The number of contacts, which is usually even, determines the width of the connector. These range from 6.3mm to 42.9mm.

The SQT-139-02-F-5 connectors are designed as a protected and slim power connection, making them ideal for use in electronic applications with limited space, such as domestic appliances, cellphones, and medical equipment. These connectors are usually used for power, with rated currents ranging from 3A to 17A. The two parts are designed to snap together, creating a secure connection.

In terms of cost, SQT-139-02-F-5 connectors are considered more expensive than other rectangular connectors, due to their size and low profile design. This is offset by their superior electrical and mechanical performance, as well as their resistance to shock and vibration in rigorous usage scenarios.

The working principle of SQT-139-02-F-5 connectors is a simple one. The socket is snapped into place on the pin, and the two parts create a mechanical and electrical connection by a series of interlocking threads before the latch locks into place. This ensures a reliable connection that can withstand a certain amount of shock and vibration without disconnecting.

SQT-139-02-F-5 connectors are a popular choice in the electronics connector industry thanks to their reliable, durable, and cost-effective design. They are used in a variety of applications where a low profile, mechanical stability, and electrical connectivity are required, including consumer electronics, automotive, industrial automation, medical equipment, and telecom.
