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](/web/c/connectors/pcb-connectors-wire-housings/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.
