SMP-SL: Self-Lock Mechanism For Extreme Aerospace And Defense Environments



HUBER+SUHNER’s SMP-SL (Self-Lock) mechanism is designed to ensure reliable electrical and mechanical performance in even the most extreme aerospace and defense environments. The unique combination of a MIL-STD-348 SMP interface together with a low-profile self-locking design provides an integral connector solution with exceptional electrical and mechanical performance.

The locking mechanism has a visual inspection feature to confirm fully mated position and perceptible click when fully mated. SMP-SL connectors can only be de-mated with a dedicated removal tool to eliminate the risk of unintentional de-mating. The connector design retains the small form factor and future proof 40 GHz frequency range of a standard SMP interface per MIL-STD-348. SMP-SL connectors are 30% smaller in size and 66% lower in mass compared to equivalent solutions available in the market.

The initial product portfolio covers the most common applications needs with cable connectors, panel mount, board mount connectors, adaptors and de-mating tools. Cable connectors are available with Space grade lightweight, low loss SUCOFLEX cables, solderless mini-bend style cables and conformable Semi Rigid cables. The SMP-SL product line has Space Flight heritage and is qualified per MIL-STD-39012.
