Honeywell GLA Series Roller Lever Limit Switch, SPDT, IP67, Die Cast Zinc Housing, 600V ac, 6A

This limit switch is a Compact actuator device designed to detect position changes and initiate control actions in industrial systems. It uses a roller lever actuator and a snap‑action contact arrangement to provide Rapid electrical switching for automation, electrical and mechanical applications. The housing is constructed from die‑cast zinc and the unit is built for installation where a robust enclosure and high ingress protection are required.

• SPDT snap‑action contact for crisp switching and clear signal change
• Switching current rated at 6A to handle moderate load circuits
• AC switching capability up to 600V for high‑voltage AC circuits
• DC switching capability up to 250V for DC control loops
• IP67 ingress protection to resist dust and water immersion
• Mechanical life of 15 million cycles for long‑term operational use

• Suitable for conveyor position detection in automated lines
• Ideal for interlock sensing on industrial machinery doors
• Used for end‑of‑travel detection on linear actuators
• Can be used for control inputs on motor starters and contactors
• Used with safety circuits requiring a Compact limit switch

The unit uses screw‑type terminals to secure field wiring and allow standard cable terminations.

It operates between −25 °C and 85 °C to suit a wide range of ambient conditions.

The roller lever operates with an actuation force of 9.5 N and the mechanism is specified for 15 million mechanical cycles to support repetitive switching tasks.

The enclosure is MADE from die‑cast zinc, offering mechanical strength and resistance to industrial wear.

The product meets CCC, UL, CSA and CE standards for recognised compliance in multiple regions.

UL/ UL listed for Canada

GLA limit switches have not been designed as emergency stop or safety devices. They must not be used in applications where personal injury could occur as a result of the products failing.

IEC/EN 60947-5-1
While IEC/EN 609747-1 covers general rules relating to low voltage switchgear and controlgear, IEC/EN 60947-5-1 specifically relates to control circuit devices and switching elements. The standard monitors the characteristics of devices, the electrical and mechanical requirements and the functional requirements.

EN50047
GLC and GLD limit switches are constructed from housing that meets EN50047. EN50047 applies to position switches with an automatic return actuator. Models that meet EN50047 feature standardised characteristics and dimensions (30.5 x 31.1 x 68 mm).

IP 66
A rating of IP 66 ensures that the limit switch units are protected against dust and low-pressure jets of water.

Sealed to NEMA 1, 4, 12, 13
NEMA 1 states that enclosures can be used indoor and offers a degree of protection against contact with the equipment enclosed.
NEMA 4 states that enclosures can be used either indoor or outdoor and provide protection against windblown rain and dust, hose directed water and splashing water.
NEMA 12 states that enclosures are intended for use indoors and offer some protection from dust, dirt, falling dirt and dripping non-corrosive liquids.
NEMA 13 states that enclosures are used indoors and offer a level of protection from oil, non-corrosive coolants, spraying water and dust.
