CIE Components in Electronics
TE Connectivity (TE), a world leader in connectivity and sensors, is celebrating 75 yearsof production of its PIDG (Pre-Insulated Diamond Grip) terminals and splices. TE’s predecessor company AMP began making PIDG products in 1943, when company founder, Uncas A. Whitaker, invented a breakthrough insulation support sleeve that offered better terminal performance under high stress. PIDG became the terminal of choice for aerospace manufacturers and quickly spread to other industries. PIDG can be found in most manufactured products where wires and cables are used including control cabinets, power supplies, transportation equipment and appliances. The many millions of PIDG terminals that are still deployed decades after installation are a testament to the rigorous testing and research that went into their design and manufacturing.
PIDG terminals and splices are designed for complete and uniform reliability in the most difficult circuit environments, with high resistance to vibration. They consist of a nylon or PVC insulation, a tin-plated copper body and a copper sleeve that crimps to the wire insulation for added support. The wire can bend in any direction without damaging the wire insulation or conductor, which is ideal for high vibration applications.
DIAMOND GRIP serrations in the insulation support barrel give maximum electrical contact and tensile strength with the conductor; and a funneled wire entry prevents turned-back wire strands for rapid wire insertion during high-speed production. The terminal insulation repels greases, oils and other hydrocarbons, and has high dielectric strength.
PIDG terminals are available in ring, spade, flag and other tongue varieties; as well as in butt and parallel splices. Wire sizes range from 26 to 10 AWG (0.12 – 6.64 mm2), standard PIDG can operate at temperatures of up to 105 degrees Celsius, while STRATOTHERM versions with fluoropolymer insulation and nickel plating are rated for use at up to 288 degrees Celsius. Operating voltage for the products is 300 V. Most PIDG is UL listed and CSA certified, and many types meet or exceed military requirement MIL-T-7928, Type II, Class 1 and 2.
