High quality 2.1mm DC bulkhead mount female power connector which are suitable for use up to +24vdc @ 5 Amps.  These connectors have been tested by Mini-Kits as being to a very high quality construction, and are used on our built products.

These connectors should not be compared to the non brand name cheap Chinese types that look similar, but fall apart when the nut is tightened, and often cannot handle much current before getting warm. 

For more information please see the CUI PJ-005A Data Sheet  Maximum panel thickness is 3mm, 2.0mm pin diameter connectors are the same as 2.1mm connectors from other manufacturers.

We can generally supply these in higher quantities than stocked in around 2 weeks POA
