Product details

Board Layout Fit: 1.25 mm Pitch, 20 Circuits, SMT

The 5054332051: The 1.25 mm pitch sets a tight board footprint — routing one trace between pads on a standard 1 oz copper layer is feasible with a 0.2 mm trace width.

Mates with the Micro-Lock PLUS 505433 receptacle housing (crimp terminals sold separately). Accepts the matching crimp terminal for 20-30 AWG wire, depending on the receptacle part selected.

Voltage rating is 50 VAC/DC. Suitable for automotive, general purpose, and industrial applications per the series listing.
