MTA connector

MTA IDC connectors by TE Connectivity AMP, work by squeezing the wire into a slot in the header, slightly narrower than the copper conductor, with a special tool. The slot slices through the insulation and squeezes tightly into the wire. This squeeze creates a gas-tight connection between freshly-scraped metal surfaces. It is a reliable and quick way of connecting as long as wire of the correct guage. No soldering, stripping or crimping is required. The header can be fitted with an optional dust cover. This fits over the top of the housing keeping it tidy and preventing the wires from being pulled out if too much force is applied to them.

MTA housings mate with MTA headers on the PCB. The MTA headers look very similar to the Molex KK ones but are not the same. Do not try an force an MTA housing onto a KK header or vice versa.
