The Multiquip 421001 Hall Effect Speed Pickup Sensor is a genuine OEM component designed for SP, PS, and CS series pavement and flat saws. This sensor is sourced directly from Multiquip, ensuring it meets the exact electrical and mechanical specifications of the original part. Compatible across a wide range of models including SP303516, SP605730, PS403030, PS706036, CS403016, CS706036, and many more in the SP, PS, and CS saw families. When your saw's blade speed monitoring system needs service, 421001 is the correct OEM replacement to restore accurate function.
Key Features
- Genuine OEM Signal Accuracy — Manufactured to the exact magnetic sensitivity and output specifications of the original sensor, ensuring accurate blade speed readings across the full operating range of your saw.
- Direct Drop-In Replacement — Matches the original mounting configuration and connector interface, allowing straightforward installation without modification to existing wiring or sensor brackets.
- Broad Saw Family Coverage — Fits a wide range of SP, PS, and CS series pavement and flat saws, including SP303516 through SP706036, PS403016 through PS706036, and CS403016 through CS706036.
- Blade Speed Monitoring Restored — A functioning Hall Effect Speed Pickup Sensor gives the operator and control system accurate real-time blade RPM data, which is critical for consistent cut depth, blade longevity, and proper engine load management.
- Operational Safety Relevance — Accurate speed sensing supports the saw's engine management and throttle control systems. A failed sensor can cause erratic speed readings or loss of blade speed feedback, compromising operator control during cutting operations.
A Hall Effect Speed Pickup Sensor detects the rotational speed of a spinning component — in this case the saw's blade drive system — by sensing the passage of a magnetic trigger through its field and converting that into an electronic signal. This signal is used by the engine management or control system to monitor and regulate blade RPM during operation. When the sensor fails or drifts out of specification, the machine may display incorrect speed readings, lose throttle feedback, or behave erratically under load — all of which reduce cutting precision and increase wear on blades and drivetrain components.
