Honeywell GLA Series Plunger Limit Switch, DPDT, IP67, Die Cast Zinc Epoxy Coated Housing, 600V ac, 6A

This limit switch is a mechanically actuated sensor designed to detect position changes within industrial systems and provide discrete electrical switching. It is built for use where a robust plunger actuator is required to convert mechanical motion into reliable snap‑action contact changes. The device is suited to installations demanding sealed enclosures and standard safety approvals in automation, electrical and mechanical environments.

• DPDT snap‑action contacts deliver flexible circuit control
• Rated switching up to 600V AC and 250V DC for high‑voltage tasks
• Switching current capacity of 6A supports control and signalling loads
• Mechanical life of 15 million cycles minimises replacement frequency
• Operating range from −25 °C to 85 °C enables varied ambient use
• IP67 die‑cast zinc housing provides ingress protection and robustness

• Suitable for conveyor end‑of‑travel detection in manufacturing lines
• Ideal for actuating safety interlocks on industrial doors
• Used with motor control systems for limit position sensing
• Can be used for machine‑tool Axis homing and overtravel protection
• Suitable for heavy‑duty packaging equipment position monitoring

It uses a plunger actuator which provides direct mechanical input to the snap‑action contacts, producing fast, repeatable switching for precise position detection.

The enclosure meets IP67, indicating complete dust‑tight protection and temporary immersion resistance suitable for harsh environments.

The device carries CCC, CE, CSA and UL listings, enabling compliance with a range of regional regulatory requirements.

A threaded conduit entry is provided to accept conduit fittings for secure cable routing and strain relief in industrial installations.

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.
