Square D 9007C54B2Y1901 Limit Switch Spdt Nc Rotary Head

Product Description

The SQUARE D 9007C54B2Y1901 is a general purpose limit switch designed for industrial position-sensing and machine control applications. It features a rotary head actuator mounted on the side of the body, a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration, and a 5-pin male terminal connection. Rated at 600 volts and enclosed in a zinc body, the switch carries an IP67 ingress protection rating, making it suitable for wet, dusty, or wash-down environments. Licensed electricians and industrial maintenance technicians typically handle installation of this device in automated equipment and control panels.

This limit switch is used in industrial and commercial settings where precise mechanical position detection is required. Common applications include conveyor systems, material handling equipment, automated machinery, and process control installations. The rotary head actuator provides 10 degrees of travel, allowing it to respond accurately to cam or lever-actuated positioning. Its operating temperature range of -20 degrees F to 185 degrees F supports use in cold storage, manufacturing, and outdoor-rated enclosures. The side-entry actuator location accommodates lateral mounting configurations where a top-entry design would not fit.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe position sensing
• Rotary head actuator with side entry location and 10-degree travel
• 600-volt rating supports a wide range of industrial control circuits
• IP67 ingress protection rating resists dust intrusion and temporary submersion
• NEMA ratings 1, 2, 4, 6, 6P, 12, and 13 cover general-purpose through watertight enclosure types
• Zinc body construction provides durability in demanding industrial environments
• RoHS compliant and tested to multiple IEC environmental and safety standards

Compatibility

Designed as an OEM-style replacement or new-installation limit switch for industrial control systems requiring a 600-volt-rated SPDT rotary head device with a 5-pin male connector and IP67 protection.

Installation Notes

Installation should be performed by a qualified electrician or licensed industrial controls technician in accordance with applicable NEC requirements. De-energize and lock out the control circuit before mounting or wiring the switch. Verify that the actuator travel alignment with the cam or trip mechanism does not exceed the rated travel range. Confirm terminal connector orientation and wiring polarity before restoring power.
