Product details

Board Fit and Contact Ratings

The B04B-ZESK-1D(T)(LF)(SN)(N): The locking ramp and full 4-wall shroud protect the rectangular pins during mating and resist vibration-induced disconnect — a solid choice for a harness that sees movement or periodic reconnection.

The ZE series offers the same 1.50 mm pitch, 2 A rating, and full shroud across 2, 4, and 5 positions. The 4-position version (this MPN) is the middle option — choose the 2-position for a minimal cable exit, or the 5-position if you need one more circuit without changing the board pitch.
