SMP Series

Blind-mate, Snap-in, & Vibration-resistant

The SMP Connectors feature a blind-mate, snap-in, vibration-resistant connection. These connectors are quick-connect/quick-disconnect connectors that are easy to mate and un-mate in small spaces, and designed to accommodate a large variety of flexible and semi-rigid cables.

Reliable Performance In Harsh Environments

The compact size allows for high density applications and, combined with the withdrawal features of the full detent design, the SMP series has become a standard for quick and effective interconnects using semi-rigid cable to printed circuit boards
