Rectangular Connectors - Headers, Receptacles, Female Sockets

SSQ-127-03-T-D-RA is a rectangular connector, referred to as a header, that consists of three pins and one connection block. It is used in many commercial and industrial applications, from industrial automation and robotics to home appliances. The SSQ-127-03-T-D-RA header is used for a variety of functions, including power, signal, and interface. The connector is designed for direct mating with complementary plugs and sockets, and it typically connects to printed circuit boards (PCBs).

Application Field

The SSQ-127-03-T-D-RA header is in wide use in almost all electronic industry. In industrial automation, the connector is used for data transmission from sensors and systems, providing glitch protection and durability for automation systems. In consumer electronics, this connector is used in home entertainment devices such as receivers, TVs, DVRs, and Blu-ray players. It is also used in household appliances such as washing machines, dishwashers, and refrigerators.The SSQ-127-03-T-D-RA header can be used for communication applications in medical, automotive, and consumer electronics. With its high durability, it is also used in military applications to provide secure connections in harsh environments.

Working Principle

The SSQ-127-03-T-D-RA header is a single-row type connector. It consists of two sidewalls, one front wall, and one rear wall. The pins and contact blocks are located inside the housing.The pins pass through the sidewalls and are locked by the front and rear walls. The contact blocks are mounted on the pins and have a bent spring section that contacts the pads on the board. When the connector is pressed into the PCB, the contact blocks move outward and make contact with the pads.The SSQ-127-03-T-D-RA header also provides a secure connection by ensuring that the pins are secured and that the contact blocks are tightly pressed into the PCB. This prevents the pins from slipping out and damages from occurring due to vibration.The SSQ-127-03-T-D-RA header is a robust and reliable connector and is ideal for applications where a secure and reliable connection is required. It is suitable for high-reliability applications and can be used in harsh environments such as industrial control systems, military applications, and home appliances.
