The Multiquip EM514216 is a genuine OEM Proximity Switch Adjustment Rod designed for the LS-series hydraulic concrete pump line, including LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, LS600P, LS300P, LS300G, and LS300GK models. As a genuine OEM component, it is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation. Sourced directly through authorized Multiquip supply channels, this rod is the right part for operators who need to restore proper proximity switch function on their concrete pump.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the rod interfaces correctly with the proximity switch mounting and adjustment mechanism on LS-series concrete pumps.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the original EM514216 rod; installs into the existing proximity switch bracket without modification to surrounding components.
- Broad LS-Series Compatibility — Fits LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, LS600P, LS300P, LS300G, and LS300GK hydraulic concrete pump models.
- Consistent Stroke Detection — Correct rod length and positioning keeps the proximity switch reading piston strokes accurately, which is essential for maintaining consistent concrete output and proper hydraulic cycling.
- Critical Sensing System Component — A worn or bent adjustment rod can cause the proximity switch to misread stroke position, leading to irregular pump cycling, output inconsistency, or system faults that interrupt pours.
The proximity switch adjustment rod is a mechanical positioning component in the concrete pump's stroke-detection system. It sets the precise gap and alignment between the proximity switch and the piston or valve actuator it monitors, allowing the control system to detect when each stroke is complete and trigger the next cycle. When this rod is bent, worn, or out of position, the proximity switch can lose its reference point — causing erratic cycling, missed strokes, or pump shutdowns that interrupt the flow of concrete during an active pour.
