Molex connectors are a great way to connect sensors and other items that need to be removable to a circuit board. This connector system uses a board mount header with a 0.156' / pitch, a matching connector housing, and pins that are crimped onto the end of each wire. The pins lock inside the housing and the housing fits onto the header. The connector is polarized, meaning it will only fit one way, and has a “locking ramp” which helps stop the connector from disconnecting unexpectedly.

These 0.156″ connectors are commonly found on power supplies and work with the 6 pin 0.156″ header.
