The high-current connectors are for units shipped before 20-Feb-2022, the standard connectors are for units shipped on or after 20-Feb-2022. PCB connectors that use the high-current connections are marked with TH, see picture.
This is a spare set of two connector housings, one 2×12 (24) and one 2×11 (22), and 50 wire terminals.
The right angle PCB plug are not included. All parts are included with the UA4C board unless purchased without.
Cameron Thomas –
What size are the old, high current connectors?
All the connectors are “3mm” type, or copies of the Molex Micro-Fit (I think their connector was first). The old ones used on the UA4C were part of the Amphenol Minitek® Pwr 3.0 HCC series which used slightly different tolerances. I think on purpose to try and prevent mating of high and low current connectors and plugs. The original micro-fit type (not high-current) was used in computers as a miniature version of the ATX connector. This means that there are many manufacturers that will all mate pretty well with each other. Just not the particular high-current version that the UA4C once used.
