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

This limit switch provides position sensing and circuit control for industrial automation and machinery applications. It uses a roller lever actuator to detect mechanical movement and transmits switching signals via a double-pole double-throw snap-action contact arrangement. The unit is housed in a solid die-cast zinc enclosure with threaded conduit entry and is suited to environments requiring protection against dust and water ingress.

• IP67-rated enclosure offers ingress protection in wet environments
• Snap-action contacts deliver fast, repeatable switching behaviour
• DPDT contact configuration enables versatile circuit arrangements
• 6A switching current supports moderate control and load circuits
• Mechanical life rated at 15,000,000 cycles reduces replacement frequency
• Operating temperature range spans -25°C to 85°C for varied climates

• Suitable for position detection on conveyor systems in factories
• Ideal for interlock monitoring on packaging machinery
• Used for end-of-travel sensing on linear actuators
• Can be used for limit detection in material handling equipment
• Suitable for signal switching in process automation panels

The outer Shell is MADE from die-cast zinc, providing Durable mechanical protection and structural rigidity.

It uses a threaded conduit entry to accept standard conduit fittings for protected cable routing.

The contacts are rated for switching up to 600VAC on alternating circuits and up to 250VDC on direct circuits.

The roller lever actuator operates with snap-action contacts and is specified for a mechanical life of 15,000,000 cycles, supporting high-frequency cycling.

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.
