Introduction

The Honeywell MICRO SWITCH GLS miniature limit switch series offers a wide range of product options for global applications. These durable and reliable limit switches are suitable for many industrial applications, agricultural equipment, transportation equipment, and other applications requiring environmentally sealed (IP and NEMA rated) switches.

The compact housing is generally well-suited for space-constrained equipment. The series is available in three different housing types: metal housing, plastic housing, or three-conduit metal housing, all complying with EN50047 mounting standards. An extensive selection of actuators, contact blocks, and conduit/connection options further enhances product versatility.

In today's demanding environment for logic-level control, electromechanical switches are frequently used to interface with PLCs and other logic-level devices. The GLS limit switches offer a gold-plated contact option for standard switches, which improves switching reliability in logic-level applications.
