Molex KK 156 3.96mm Connector Kit — Male & Female Housing with 20AWG PVC Pre-Crimped Cables

Molex KK 156 3.96mm Connector Kit — Male & Female Housing with 20AWG PVC Pre-Crimped Cables

The Molex KK 156 3.96mm connector is the industry-standard wire-to-board connector for power supply internal wiring, industrial control panels, and high-current PCB connections. With a 3.96mm pitch and 8.5A / 250V AC/DC rating, the KK 156 series bridges the gap between the compact 2.54mm Dupont connector and the heavy-duty 4.2mm Mini-Fit Jr., making it ideal for medium-current power and signal connections in a wide range of electronics applications.

This kit includes male housings, female housings, and 20AWG PVC pre-crimped wire assemblies in assorted pin counts, providing a complete wire-to-board and wire-to-wire connection solution without the need for a crimping tool.
