Parker PPS1-1C3-RHM Pressure Switch
Parker PPS1-1C3-RHM high-performance, field-adjustable pressure switch is designed for critical pneumatic systems. Featuring a rugged brass body and a long-life elastomer diaphragm, it provides a reliable SPDT electrical output when system pressure reaches your specific rising set point.
Description
Parker PPS1-1C3-RHM pnuematic pressure switch is engineered for industrial environments requiring precise pressure regulation and compact form factors. This unit utilizes a high-quality snap-action switch to ensure distinct electrical transitions, minimizing “chatter” and extending the operational life of your control circuits.
With a factory-calibrated rising set point and a field-adjustable range of 20 to 120 psi, this switch offers the flexibility needed for diverse automation tasks. The integrated DIN 9.4 mm (HM style) electrical connection provides a secure, vibration-resistant interface, while the 1/4″ NPT Male thread ensures seamless integration into standard North American pneumatic manifolds.
Key Performance Benefits
- Enhanced Durability: Rated for 1 million cycles, reducing maintenance intervals in high-duty cycle applications.
- Environmental Protection: Meets NEMA 4 and 13 (IP66/IP54) standards, protecting internal components against moisture and oil mist.
- Broad Compatibility: Brass construction and Nitrile (NBR) seals are compatible with standard lubricated or non-lubricated compressed air.
