PCB Sockets are connectors that are designed to allow the connection of two printed circuit boards (PCBs) without cabling. They’re connected to a PCB to ensure a more secure and stable connection. PCB sockets (female) and PCB headers (male) are used in a pair, one mating and unmating in what is referred to as a mating cycle.They are utilised in applications where PCB’s are required to easily connect and disconnect to allow design flexibility and simplified assembly.How do PCB sockets work?PCB sockets work by receiving the male end of the connector on one side and connecting to a second PCB on the other. Each socket includes a housing and a specific number of terminals. The housing is made from insulating material while the terminal is made from a conductive material and plated to improve antirust and conductivity.What are PCB sockets used for?PCB sockets are used in a wide range of circuit board applications and can be used as alternatives to soldering relays directly to a PCB, allowing for easy replacement of timers or relays.
