Honeywell Technologies GLA Series Adjustable Roller Lever Limit Switch, 2 NC, IP67, Die Cast Zinc Epoxy Coated Housing,

This limit switch is a rugged mechanical device designed to detect and control position in industrial systems. It employs an adjustable roller lever actuator to provide repeatable end-of-travel signalling for automated machinery and safety interlocks. The unit is built for demanding environments with a sealed housing and standard electrical switching ratings suitable for both AC and DC control circuits.

• Die-cast zinc housing provides robust protection against impact
• IP67 ingress rating allows operation in wet or dusty locations
• 2 NC slow-action contacts support stable switching behaviour
• Rated for 600V AC and 250V DC to handle common control voltages
• Mechanical life of 15 000 000 cycles minimises replacement frequency
• Operating range from −25 °C to 85 °C enables high-temperature deployment

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for limit sensing on industrial packaging machinery
• Used with motor starters for position-based isolation in plants
• Can be used for gate and door position monitoring in outdoor sites
• Used for actuation feedback in assembly automation systems

It accepts an M20 conduit entry allowing standard metric gland fittings and straightforward cable routing in control panels.

The adjustable roller lever permits fine tuning of actuator position for precise trip points and accommodates varying cam or follower geometries.

The slow-action contact pair is rated for 6A switching current, suitable for direct control of many relays and contactors within its voltage limits.

With a specified mechanical life of 15 000 000 cycles, it supports long-term operation in high-cycle applications, reducing maintenance intervals.

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.
