Sender, mechanically driven, dual output, fits SAE tachometer drive on diesel engines.
A dual output (four wire) mechanical sender. It attaches to a tachometer drive fitting on many diesel engines and produces 8 pulses per revolution.
Dual output senders and sensors (two pairs of output wires) are typically used when an auxilliary instrument, such as an electronic engine control, requires engine speed input.
For use with models 8402 & 8905 Digital Tachometers.
