The Multiquip EM514208 Proximity Switch Support Bar is a genuine OEM component designed for Mayco hydraulic-driven concrete pump models LS300, LS400, LS500, LS600, LS40D, LS40TD, and LS50TD. As a direct OEM replacement, EM514208 is manufactured to the exact tolerances and mounting specifications of the original part, ensuring the proximity switch sits in the correct position relative to the hydraulic system components. Sourced directly through Multiquip's authorized parts network, this bar is the correct choice when performing sensor-related service or rebuilding the switching assembly on LS-series concrete pumps.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original dimensional and material specifications, ensuring the proximity switch is held at the precise standoff distance required for accurate signal output.
- Direct Mounting Compatibility — Engineered to bolt directly into the existing mounting points on LS-series concrete pumps with no rework to surrounding hardware or brackets.
- Broad LS-Series Fitment — Confirmed fit for LS300, LS400, LS500, LS600, LS40D, LS40TD, and LS50TD Mayco hydraulic concrete pumps.
- Supports Accurate Stroke Detection — Holds the proximity switch in stable alignment so the pump's hydraulic cycle is detected correctly, keeping concrete output consistent and piston timing on spec.
- Long-Term Structural Integrity — Built to withstand the vibration and hydraulic pressure cycles generated during continuous concrete pumping operation without flexing or shifting.
The proximity switch support bar is a structural mounting component that holds the proximity switch in a fixed, precise position within the hydraulic pumping circuit of an LS-series concrete pump. The proximity switch itself reads piston or valve movement to control hydraulic sequencing — if the support bar is bent, cracked, or missing, the switch can shift out of alignment, causing missed or erratic trigger signals that disrupt pump stroke timing. Replacing a damaged or worn EM514208 restores the switch to its correct orientation and ensures the hydraulic system cycles reliably during pumping operations.
