Honeywell Technologies GLA Series Roller Lever Limit Switch, 2 NO/2 NC, IP67, Die Cast Zinc Epoxy Coated Housing, 600V

This limit switch offers robust switching for industrial automation and control tasks, delivering snap-action contact operation via a roller lever actuator. It is housed in a die-cast zinc enclosure with ingress protection suitable for harsh environments, and supports side mounting for integration into mechanical systems.

• 2NO and 2NC contacts provide versatile signalling options
• Snap-action contacts enable fast, repeatable switching performance
• Rated for 10A switching current to handle moderate loads
• Operates up to 600VAC for high-voltage control circuits
• Mechanical life of 15 million operations reduces replacement frequency
• Temperature range from -25 to 85°C maintains function in extremes

• Suitable for position sensing on automated conveyors
• Ideal for end-of-travel detection in electric actuators
• Used with industrial Gates and safety interlocks
• Can be used for limit detection in assembly lines
• Used for signalling in motor control cabinets

The unit accepts 1/2-14 NPT conduit fittings to accommodate standard threaded wiring connections.

It is designed for side mounting to align the roller lever with lateral actuating elements.

Certification includes CSA, EN, IEC, RoHS, UL, CCC and CE, indicating compliance with multiple regional standards.

The enclosure is MADE from die-cast zinc, offering structural strength and environmental resistance.

It is rated for switching up to 250VDC, enabling use in DC control and signalling applications.

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.
