12-Position, 3-Row Sealed Receptacle Housing
The 1903720-1 is a 12-position, 3-row receptacle housing from TE's Power Double Lock series, on a 3.96mm pitch with a 4.60mm row spacing. The housing is sealed and includes a double lock plate, which provides secondary terminal retention and environmental protection — a key feature for applications where moisture or vibration could compromise the connection.
Sealed Construction and Locking Mechanism
The sealed design, combined with the latch holder fastening type, makes this housing suitable for wire-to-board applications in automotive, industrial, and appliance environments where the connector must resist ingress and stay mated under vibration.
