This specification covers performance, tests and quality requirements for the TE Connectivity (TE)
MTA-.156 Quad Contact connector system. This connector system can be mass or single wire
terminated utilizing insulation displacement technology on .156 inch centerlines and mates with .045
inch square posts. This system provides a reliable interconnection between wires and posts mounted
on printed circuit boards. Quad connector is available in 2 through 12 positions. This connector system
is designed to be terminated to 18, 20 and 22 AWG wire, solid, stranded and prefused or overcoated
wire, tin plated, UL style 1007, 1061 or wire which specifies PVC insulation with temperature rating
compatible with specified operating temperatures, see Figure 4A. Wire shall be applied per application
requirements specified in Application Specification 114-1048. Wire insulation diameter shall be .070
inch maximum OD for mass terminated wire and .095 inch maximum OD for single terminated wire.
1.2.
Qualification
When tests are performed on the subject product line, procedures specified in Figure 1 shall be used.
All inspections shall be performed using the applicable inspection plan and product drawing.
