The Multiquip EM97025 Cable Proximity Switch is a genuine OEM component designed for ST-45HRM and ST-70 series concrete pumps. As a direct OEM replacement, this switch is built to the same specifications as the original part, ensuring correct signal output and reliable detection performance in demanding concrete pumping applications. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence knowing it will install and perform as the original did.
Key Features
- OEM-Matched Signal Accuracy — Manufactured to the same electrical output and sensing specifications as the original, ensuring the pump's control system receives precise positional feedback.
- Direct Plug-In Installation — Designed to connect using the factory wiring harness and mounting points on ST-45HRM and ST-70 units, requiring no splicing or bracket adaptation.
- Confirmed Fitment — Verified for ST-45HRM and ST-70 concrete pumps; always cross-reference your model and serial number before ordering.
- Consistent Pump Cycle Control — A correctly functioning proximity switch keeps concrete pump strokes timed accurately; a failed switch can cause erratic cycling, missed strokes, or complete pump shutdown.
- Operational Safety Relevance — In concrete pump systems, proximity switches are part of the stroke-control circuit; using a correctly rated OEM replacement helps maintain safe, predictable machine operation.
A cable proximity switch is a non-contact position sensor that detects the presence or movement of a target — typically a piston or valve component — within the pump's hydraulic or mechanical cycle. In a concrete pump, it sends an electronic signal to the control system to trigger the next stroke, keeping the pumping action smooth and synchronized. When this switch fails or drifts out of calibration, the pump may cycle erratically, lose output consistency, or stop altogether, making prompt replacement critical to keeping pours on schedule.
