The 36783-1201 is a 12-way 2-row right angle MX120G? Sealed Header Connector Assembly with tin-plated brass contacts. This 42377 series PCB header comes with a nylon resin housing and through hole termination. It mates with 36792-1201 3.20mm MX120G? pitch sealed female connector assembly. Molex's MX120G? connector system is a highly compact, sealed, wire-to-wire and wire-to-board family of interconnects that delivers optimal performance especially in wet, high-vibration and wide-operating-temperature conditions. Designed for rugged, harsh environment non-automotive applications, the IP67-rated, MX120G interconnect system can be extended to exterior lighting applications that include traffic and overhead street lights and is a more reliable and less expensive solution to pre-crimped wire-seal alternatives. It is suitable for wire-to-board application.
