The 30.0µin gold-over-phosphor bronze contacts give the mating interface corrosion resistance and cycle life for field-service connections — gold at this thickness handles hundreds of mate-unmate cycles without fretting, which matters when the cable end gets swapped during maintenance. ## Mounting and Termination Check Through-hole right-angle mounting: the solder tails insert into the PCB and are wave-soldered. The 0.318\" (8.08mm) backset spacing sets the distance from the PCB edge to the mounting flange face — confirm this dimension against your enclosure wall thickness and the mating plug's cable bend radius before laying out the board. The 4-40 threaded insert accepts standard D-sub hardware; torque to 0.3–0.5 N·m per industry practice, not more.","metaTitle":"TE 745783-4 AMPLIMITE HD-20 D-Sub Receptacle, 25 Pos, R/A","metaDescription":"TE Connectivity 745783-4 AMPLIMITE HD-20 D-sub receptacle, 25 positions, right-angle solder, 6A, 125V, 30µ\" gold.
