Honeywell GLA Series Roller Lever Limit Switch, 1 NO/1 NC, IP67, Die Cast Zinc Epoxy Coated Housing, 600V ac, 10A

This limit switch is a Compact electromechanical device designed to detect position changes and provide discrete control signals in industrial systems. It is intended for use where a robust, externally actuated switch is needed to monitor movement or presence within automation, electrical and mechanical installations. The unit is compatible with conduit entries common to industrial wiring and offers environmental protection suitable for demanding workplaces.

• Die-cast zinc housing provides corrosion-resistant protection
• IP67 rating allows operation in wet and dusty environments
• Snap-action contacts deliver fast, reliable switching
• 10A switching current supports moderate load circuits
• 600V AC switching capability accommodates high-voltage control
• Mechanical life rated at 15 million operations reduces maintenance frequency

• Suitable for conveyor end-of-travel detection in factories
• Ideal for limit detection on industrial actuators and valves
• Used with motor control panels for position feedback
• Can be used for safety interlocks in machinery assemblies
• Suitable for automated packaging equipment position sensing

It employs a roller-lever actuator that converts mechanical movement into contact operation suitable for cam or follower interfaces.

The unit provides a changeover contact arrangement with one normally open and one normally closed contact to manage separate control paths.

The device functions across an ambient span from -25 °C up to a maximum of 85 °C, suitable for many industrial environments.

It is designed for side mounting to accommodate space-restricted panels and equipment layouts.

It accepts NPT conduit entries sized 0.5 to 14 to integrate with standard industrial wiring systems.

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.
