AMP wire pins are available both insulated and uninsulated. The insulated wire pins employ an insulating sleeve to provide strain relief and to prevent shorting between adjacent pins on close centerline applications. Both insulated and uninsulated product is available in a wide range of wire sizes. Only minimal resistance is added by the wire pin, making it electrically "invisible". Wire pins are available in the following AMP product styles: PIDG, PLASTI-GRIP, TERMINYL, SOLISTRAND and DIAMOND GRIP terminals & connectors. All pins are constructed of tin plated copper.
