Overview
Honeywell GLAC20C is a heavy-duty general-purpose limit switch in the MICRO SWITCH GLA Series, designed to global EN50041 standards and well suited for worldwide applications. The rugged die-cast metal housing of the switch is ideal for indoor and outdoor applications where a degree of IP or NEMA enclosure sealing is required.
Key Features
- DPDT snap action contacts with 2NC 2NO configuration providing dual switching capability
- Top roller plunger actuator for reliable engagement and disengagement
- Modular design with interchangeable heads, actuators, bodies, and contact blocks for rapid customization
- Rugged die-cast metal housing for harsh indoor and outdoor environments
- IP67 sealing protecting against dust and temporary submersion
- UL/CE/CCC certifications for global market compliance

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The GLAC20C serves as a direct replacement for earlier Honeywell MICRO SWITCH GLA units with identical 30×60 mm mounting footprint and 2NC/2NO contact arrangement. Related models in the GLA series include GLAA20C (silver-alloy contacts) and GLAC01C (1NC/1NO configuration), though electrical and mechanical specifications may differ.
Works With
- Screw-terminal and conduit connection options (threaded G1/2 and PG13.5 entries available)
- Industrial control wiring and hardwired automation circuits
- Compact wiring harnesses and panel layouts using standard limit switch connectivity
- Diagnostic LED pilot lights (optional on related GLA series variants)
