Parker PXC-M121 Pneumatic Limit Switch

Parker PXC-M121 Pneumatic Limit Switch – Key Features

1. Function:
   • Mechanical limit switch with pneumatic signal output (air-piloted).
   • Detects actuator/cylinder position and sends a pneumatic signal to control circuits.
2. Operation:
   • Normally closed (NC) or normally open (NO) configurations (model-dependent).
   • Adjustable roller lever for precise actuation positioning.
3. Ports & Pneumatics:
   • Supply port: 1/8" NPT (typical).
   • Output port: 1/8" NPT (pneumatic signal output).
   • Operating pressure: 20–120 psi (1.4–8.3 bar).
4. Mechanical Specifications:
   • Housing: Durable aluminum or stainless steel.
   • Actuation force: ~2–5 N (adjustable lever sensitivity).
   • IP65/IP67 (dust/water resistant for harsh environments).
5. Electrical Compatibility:
   • Interfaces with pneumatic control systems (no electrical components, purely air-piloted).
6. Temperature & Environment:
   • Operating temperature: –20°C to +80°C.
   • Suitable for explosive atmospheres (if certified for ATEX/IECEx).

Typical Applications

✔ Pneumatic cylinder end-position detection.
✔ Safety interlocks in machinery.
✔ Hazardous environments (oil & gas, chemical plants).
