2 Pin Micro Circular Underwater Connector -- MCBH2F & MCIL2M | IP69K | Power & Signal
Shanghai Kabel Intelligence Technology Co., Ltd supplies 2-contact micro circular wet-mateable underwater connectors including MCBH2F (bulkhead female) and MCIL2M (in-line male). The 2-contact format is the simplest and most compact in the Micro Circular platform -- dedicated to single-circuit DC power supply, sensor output lines, or simple on/off control signals. Rated to 7,000 m depth, IP68/IP69K sealed.

Frequently Asked Questions
Does MCBH2F mate with SubConn MCIL2M?
Yes. Shanghai Kabel MCBH2F mates directly with OEM SubConn MCIL2M -- identical mating interface.
Why use a dedicated 2-pin connector instead of piggybacking on unused contacts in a larger connector?
A dedicated 2-pin connector simplifies fault isolation, allows independent disconnection of one circuit without disturbing others, and reduces per-contact current sharing issues in high-power circuits (up to 20 A total for 2 x 10 A contacts).
Is a 2-pin connector available in stainless steel?
Yes, MCBH2M-SS and MCBH2F-SS are available. Contact sales@rovcable.com for pricing.
