320569 is a PIDG closed ring tongue terminal. It is designed for uniform reliability in the harshest circuit environments, especially where high vibration and wire movement are factors. It consists of a nylon or PVC insulated body, plus a metal sleeve that crimps to the wire insulation for added support. The wire barrel design is vibration resistant and supports the wire to bend in any direction without damaging the wire insulation or conductor. Typical applications are instruments/control, lighting, power supplies, panel boxes, transportation, lifting equipment, motors, aerospace, and appliances.
