Square D L100WS2M2 Limit Switch Dpdt Nc 600V Rotary

Product Description

The SQUARE D L100WS2M2 is a general purpose limit switch configured as DPDT with normally closed contacts and a rotary spring return actuator mounted on the side of the unit. Rated for 600 volts, it is built for industrial and commercial control circuits where reliable position sensing and automatic actuator return are required. The aluminum body carries an IP67 ingress protection rating, making it suitable for environments exposed to dust and water. A 1/2 inch NPT conduit connection and side-mounted screw terminals simplify field wiring. Electricians and industrial control technicians install this switch in machinery, conveyor systems, and HVAC air-handling equipment to detect component travel or end-of-travel positions.

The L100WS2M2 is appropriate for use in both light industrial and commercial installations where a NEMA 1, 2, 4, 12, or 13 rated enclosure-grade switch is required. The rotary spring return mechanism provides 17 degrees of travel and automatically resets the actuator when the operating force is removed. Its temperature range of -10 degrees F to 185 degrees F covers most indoor mechanical equipment rooms and plant floor environments. Side actuator placement suits installations where the triggering cam or rod approaches the switch from the lateral axis.

Key Features

• DPDT contact form with normally closed configuration for standard interlock and position-sensing circuits
• Rotary spring return actuator with 17 degrees of travel auto-resets on release
• IP67 ingress protection rating resists dust ingress and temporary water immersion
• NEMA ratings 1, 2, 4, 12, and 13 cover a broad range of enclosure environments
• 600-volt rating accommodates standard industrial control voltage levels
• Aluminum body construction with 1/2 inch NPT conduit entry and side screw terminals for straightforward wiring

Compatibility

Designed as an OEM-style replacement or new-installation general purpose limit switch for industrial control panels, machinery, and commercial mechanical systems requiring a DPDT NC rotary spring return actuator in a NEMA 1, 2, 4, 12, or 13 rated package.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the circuit before mounting or wiring the switch. Use the 1/2 inch NPT conduit connection with an appropriate fitting and seal where moisture ingress is a concern. Verify actuator alignment and travel clearance before restoring power to confirm reliable operation without overtravel damage.
