Core Advantages that Deliver Unmatched Durability
Full Series & Flexible Pin Counts

Choose from the complete MS3116 lineup, with 2 to 61 contacts (1.6mm/2.3mm diameters) to support both low-density signal setups and high-density power/signal integration. Popular models include MS3116F14-19S (19-pin) for mid-range signal transmission, MS3116F18-32S (32-pin) for multi-channel systems, and MS3116F24-61S (61-pin) for high-density applications.

MS Electrical Connector


Harsh-Environment Ready

IP67 waterproof/dustproof sealing, -55℃ to +125℃ operating temperature range, and aluminum alloy housing that resists vibration, salt spray, and corrosion—ideal for outdoor, marine, and battlefield deployments.

38999 Connector


High-Density, Stable Performance

≤2.5mΩ contact resistance, 600V AC rated voltage, and 1500V AC dielectric withstand (1 min)—ensuring consistent signal/power transmission even in extreme conditions. PBT/epoxy insulation materials enhance electrical safety and long-term reliability.

Female Connector


Fast, Secure Mating

3-pin bayonet lock enables anti-mislocation, one-handed coupling (500+ mating cycles) for quick field installations, reducing downtime during maintenance and replacement.

MS Connector


Ideal For
Aerospace avionics, military ground vehicles, radar systems, marine equipment, and industrial control panels - any scenario demanding military-grade ruggedness in a compact form factor.
