2659034 Sensor Gp-Speed Fits Caterpillar Models

One New Aftermarket Replacement Speed Sensor (Sensor Gp-Speed) for Caterpillar (Cat) Industrial and Power Systems Engines

This aftermarket replacement Sensor Gp-Speed (265-9034) monitors engine crankshaft rotational speed and provides critical speed and top-dead-center reference signals to the Caterpillar ADEM or A4 Electronic Control Module (ECM), enabling precise fuel injection timing and engine synchronization. The sensor uses magnetic reluctance (variable reluctance) technology, generating an AC voltage waveform as teeth on the timing gear or flywheel pass the sensor tip. It features a shielded cable with connector termination for reliable signal integrity in high-EMI environments such as power generation plants and mining sites.
