Square D 9007CR53B Explosion Proof Limit Switch

The Square D 9007CR53B explosion-proof limit switch is a heavy-duty hazardous-location device rated up to 600 VAC and 10 A (600 VDC 2.5 A) with SPDT contacts (1NO-1NC). Housed in a die-cast zinc alloy enclosure, it is UL/CSA listed and CE-marked for Division 1/Class I (Groups B, C, D) and Class II (Groups E, F, G) hazardous locations, and is compatible with a broad range of NEMA configurations: 1/2/4/6/6P/7/9/12/13. The unit accepts a 1/2 in NPT conduit entry and uses a rotary head/lever actuator for 90-degree actuation, suited for plug-in or surface installations in harsh environments. Operating temperature ranges from -20 to 185 degrees Fahrenheit, and the switch is designed for oil-tight and water-tight service in facilities such as chemical plants and refineries that require explosion-proof protection.
