This is a 2-pin, Wired SH series JST male connector and it comes with mating through receptable. The pins are spaced by 1mm. We really like the solid locking feeling and high current rating on these small connectors. Great for jumping from board to board or just about anything else. They have bare wires on one end and a 2-pin JST SH connector on the other end with a mating socket. Male and Female Connector comes as a set in the same pack. The whole length of the connector with wire comes as 150mm.
