These share the same "MCBH21" designation in different series -- the Circular Series variant (listed here) uses a larger shell diameter than the Micro Circular MCBH21 from Cat30 and has different mating dimensions. Always confirm the exact series (Micro Circular vs. Circular) when ordering to ensure correct mating compatibility.
Yes. Dummy caps are available for all 21-pin bulkhead models and should be fitted during transit, storage, and any period when the connector is unmated underwater. Specify quantity when ordering.
