Overview
The CCS 604GZM2 is an adjustable diaphragm-type pressure switch engineered for industrial process control and monitoring. It combines Dual-Snap® disc spring technology with a robust design for applications demanding high reliability and vibration resistance. With a 4500 PSIG proof rating and field-adjustable setpoints from 6 to 75 PSIG, this switch delivers stable, repeatable performance across demanding environments.
Key Features
- Dual-Snap® Belleville disc spring mechanism: Pioneered by CCS, this technology ensures crisp switching action and extends cycle life by reducing premature wear.
- Field-adjustable pressure range: 6–75 PSIG setpoints with calibrated adjustment wheel for easy on-site commissioning.
- High proof rating: 4500 PSIG proof rating handles system spikes and transients.
- NEMA 4 / IP65 enclosure: UL-listed design protects against dust and water ingress, suitable for washdown and outdoor environments.
- Vibration and shock resistant: Integral design minimizes false switching from mechanical disturbance.
- High cycle life: Robust contacts and spring mechanism support extended operational life.

Compatibility & Replacements
Compatible With
- Industrial PLC and relay control systems (24 VDC to 250 VAC logic)
- Pneumatic and hydraulic systems operating 6–75 PSIG
- Panel-mount and field-mount installations via 3/4″ NPT port
- Standard industrial electrical enclosures (screw-terminal wiring)
Replaces / Drop-In Replacement For
- CCS 604G and 604G2 variants in similar pressure ranges
