Product details

The crimp termination is a field-reliable method: strip, crimp, insert until the lance locks. No soldering in the harness.

Active Lifecycle — No Obsolescence Pressure

There is no end-of-life notice, no last-time-buy date to track.

Pitch and Position Count — Board Fit Check

At 0.156" (3.96mm) pitch, this housing matches the standard SL-156 header footprint. The 24 positions in a single row give a total body width of about 3.74 inches (95 mm) across the mating face. That is a wide connector — plan for board real estate and wire bundle routing accordingly. The pitch is generous enough for 18-22 AWG wire without crowding the crimp pockets.
