Honeywell Technologies GLA Series Adjustable Roller Lever Limit Switch, 1 NC/1 NO, IP67, Die Cast Zinc Housing, 600V ac,

This limit switch provides mechanical position sensing for industrial control systems, delivering snap-action contact switching in demanding environments. It is intended for side-mounted installations where a compact, watertight actuator is required and supports both AC and DC switching duties for automation, electrical and mechanical equipment.

• Snap-action contacts provide Rapid state change and clear signalling
• 1NC and 1NO contact arrangement offers flexible circuit options
• IP67 ingress protection enables use in wet or dusty locations
• Electrostatic epoxy-coated zinc housing resists corrosion in harsh sites
• Rated for 600V AC and 6A to handle common control voltages
• High mechanical life of 15,000,000 operations reduces replacement frequency

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for gate and valve position feedback in process plants
• Used with packaging machinery for stroke-limit monitoring
• Can be used for safety interlocks on machine guards
• Suitable for actuator position sensing in electrical switchgear

It employs an adjustable roller lever actuator that allows fine alignment of the contact point and is designed for side-oriented mounting to suit linear travel mechanisms.

Wiring is fed through an M20 conduit entry to maintain enclosure integrity and permit standard industrial conduit fittings.

The device is specified to function between -25°C and 85°C, supporting applications exposed to low and elevated ambient temperatures.

It conforms to several recognised standards including CE, UL, CSA and CCC to align with international regulatory expectations.

The snap-action contact mechanism combined with a robust housing contributes to the listed mechanical endurance for prolonged duty cycles.

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.
