Square D 9007CR53B2 Limit Switch Spdt Nc Rotary Head 600V

Product Description

The SQUARE D 9007CR53B2 is a general purpose limit switch designed for industrial position-sensing applications. It features a single-pole double-throw (SPDT) contact form in a normally closed (NC) configuration, rated for up to 600 volts. The rotary head actuator is side-mounted with a 6.4-inch actuator length and operates through a 10-degree travel range. The body is constructed from aluminum and zinc for durability in demanding environments. It carries an IP67 ingress protection rating, making it suitable for locations exposed to dust, debris, and temporary immersion. Licensed electricians and industrial maintenance technicians are the primary installers for this type of device.

This limit switch is suited for use in manufacturing, material handling, conveyor systems, and other industrial machinery where precise position detection is required. It performs reliably across a wide temperature range, from -20 degrees F to 185 degrees F, supporting both indoor and outdoor industrial installations. The screw terminal connection type simplifies field wiring during installation or replacement. Its compact body dimensions of 2.72 inches wide by 2.79 inches deep allow it to fit in tight panel or machinery mounting locations.

Installation Notes

Installation should be performed by a qualified electrician or licensed industrial maintenance technician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before removing or installing this switch. Secure mounting and proper alignment of the rotary actuator with the target cam or trip mechanism are critical for reliable operation. Verify all screw terminal connections are tight and insulation clearances meet code requirements before restoring power.
