TE Connectivity (TE) celebrated 75 years of 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.
