Shanghai Kabel Intelligence Technology Co., Ltd 4-contact right-angle micro circular connectors MCBHRA4M/MCIL4F. IP68, 7000m, 90-degree body. SubConn MCBHRA4 compatible. For space-constrained ROV panel installations.

Product introduction

4 Pin Right Angle Micro Circular Underwater Connector -- MCBHRA4M & MCIL4F | ROV Subsea | IP68

Shanghai Kabel Intelligence Technology Co., Ltd supplies 4-contact right-angle micro circular underwater connectors including MCBHRA4M (right-angle bulkhead male, 10 A) and MCIL4F (in-line female). The 4-contact right-angle configuration is favoured in ROV and AUV chassis where a 90-degree cable exit is required and where 4 conductors -- typically 2 power + 2 signal -- are sufficient for the application.

Rated to 7,000 m depth, IP68, SubConn® MCBHRA4/MCIL4 compatible.

Available Models -- 4 Contact (Standard and Right Angle)

Part Number Type Gender Notes
MCBH4M Straight Bulkhead Male (pins) Standard
MCBH4F Straight Bulkhead Female (sockets) Standard
MCIL4M In-Line Male (pins) Standard
MCIL4F In-Line Female (sockets) Standard
MCBHRA4M Right-Angle Bulkhead Male (pins) 90-degree, 10 A/contact
MCBHRA4F Right-Angle Bulkhead Female (sockets) 90-degree
MCDC4F Dummy Cap -- Protective

Frequently Asked Questions

Does MCIL4F mate with MCBHRA4M?

Yes. The right-angle MCBHRA4M bulkhead uses the same contact face as the straight MCBH4M, so standard MCIL4F in-line connectors mate with it directly.

Does MCBHRA4M mate with SubConn MCIL4F?

Yes. SubConn MCIL4F mates directly with Shanghai Kabel MCBHRA4M -- no modification needed.

Why choose right-angle (MCBHRA) vs straight bulkhead (MCBH)?

Right-angle reduces the depth footprint behind the panel wall. Use MCBHRA when the housing internal depth is less than the straight MCBH cable clearance requires, or when cables must exit parallel to the panel for routing reasons.
