Multiquip V862251 Tachometer Sensor

The Multiquip V862251 Tachometer Sensor is a genuine OEM component designed for the DCA400SSV ultra-silent diesel generator series. As a direct OEM replacement, this sensor is sourced and specified to the same standards as the original part installed at the factory, ensuring it integrates correctly with the generator's monitoring and control systems. Verified fitment for the DCA400SSV makes this the straightforward choice when restoring accurate engine speed measurement to your machine.

Key Features

• OEM-Accurate Signal Output — Manufactured to the exact electrical specifications required by the DCA400SSV control system, ensuring the tachometer reads engine RPM correctly without calibration adjustments.
• Direct Drop-In Replacement — Matches the original mounting configuration and connector type, allowing a straightforward swap without additional adapters or modifications to existing wiring.
• Confirmed Fitment for DCA400SSV — Verified for the Multiquip DCA400SSV ultra-silent diesel generator, so you can order with confidence that this is the correct sensor for your unit.
• Protects Generator Load Management — Accurate RPM data is critical for maintaining stable power output under load; a failed or drifting sensor can cause erratic governor response and voltage instability.
• Genuine Multiquip OEM Part — Supplied as a genuine Multiquip replacement, backed by the manufacturer's parts program and sold through DHS Equipment as an authorized distributor.

The tachometer sensor monitors crankshaft or flywheel rotation speed and transmits that signal to the generator's control panel and governor system. This real-time RPM data allows the engine management system to maintain a consistent output frequency — critical for sensitive equipment running on generator power. When the sensor fails or produces an inaccurate signal, the governor loses its reference point, which can lead to unstable engine speed, frequency fluctuation, or fault shutdowns that interrupt power delivery entirely.
