Parker PPS1-2C3-RHM Pressure Switch
Parker PPS1-2C3-RHM field-adjustable pneumatic pressure switch is designed for precise system monitoring. Featuring a 20-120 PSI range and a robust SPDT circuit, it ensures reliable electrical output for CNC and automation safety loops.
Description
The Parker PPS1-2C3-RHM (PPS1 Series) is a mission-critical sensor for industrial air systems. Engineered by Parker’s Pneumatic Division, this switch monitors line pressure and triggers an electrical signal when the set point is reached. It is essential for protecting expensive CNC spindles and actuators from low-pressure conditions. Constructed with a durable brass body and a high-quality Nitrile (NBR) diaphragm, the PPS1-2C3-RHM is built for a service life of over 1 million cycles. Its compact footprint and 1/8″ NPT male thread allow for direct installation into manifold blocks or gauge ports without the need for additional brackets.
Engineering Advantages
- Field Adjustability: Easily calibrate the set point using an anodized aluminum knob to match specific application requirements.
- Snap-Action Reliability: Features a high-quality SPDT (Single Pole Double Throw) switch for crisp, repeatable electrical triggering.
- Environmental Protection: Rated for NEMA 4 and 13 (IP66/IP54), making it suitable for washdown environments and oil-mist exposure.
