Proximity Switch 1-18755 Water Jet Cutting Machine Pump Parts

The Proximity Switch 1-18755 is a non-contact sensing component used in Waterjet Intensifier pump systems. Its main function is to detect the position or movement of internal mechanical components, such as the piston or shift mechanism, and send accurate electrical signals to the control system for automated operation and monitoring.
This proximity switch helps control the intensifier cycling process by providing real-time position feedback, ensuring proper pump shifting, stable pressure generation, and safe system operation. It is designed for reliable performance in industrial environments with vibration, pressure fluctuations, and continuous operation.
A high-quality proximity switch is essential for maintaining automation accuracy, improving pump reliability, and reducing unexpected downtime.

Is Proximity Switch 1-18755 a Wear Part?

Yes — the Proximity Switch 1-18755 is considered a semi-wear electronic component.
Although it operates without direct mechanical contact, it continuously works in harsh industrial conditions involving vibration, electrical load, temperature variation, and repeated operating cycles. Over time, the sensing performance or internal electronics may degrade or fail.
If not replaced when malfunctioning, it can cause inaccurate position detection, shift timing errors, unstable pump operation, and control system faults.
Regular inspection and functional testing are strongly recommended.
