The GLA series of limit switches belongs to part of the wider GLS range of general purpose limit switches from Honeywell. The GLA Series is a non-plug in solution with a rugged metal construction. These limit switches been designed for worldwide applications and meets the global EN 50041 standard for switch mounting centres.

• Both normally closed (NC) snap actions contacts and normally open (NO) slow action contacts are positive opening.

• GLA limit switches have a modular design. The bodies, actuators and contact blocks can easily be adjusted, allowing you to customise the unit to suit your application. The models are available with different conduit options enabling them to be used for global applications.

Suitable applications for GLA limit switches include:
• Aerial lifts and boom lifts
• Assembly lines, conveyors, cranes, elevators and hoists
• Construction equipment and machinery, including vehicles and lift trucks
• Material handling and machining tools
• Textile machinery
• Packaging equipment
• Transportation hubs
• Valves
• Railroad signalling equipment and locomotives
• Apertures and doors

Yes, all of the levers that make up side rotary assemblies can be purchased as replacement parts. All switch heads that meet standard EN 50041 can be removed and replaced.

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.

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.

This snap-action limit switch from Honeywell acts as a sensor for the presence of objects in mechanical systems. It triggers a change in the electrical state by controlling the side rotary lever to physically detect the position of the target. The metal body is made of electrostatic, die-cast epoxy-coated zinc, which offers reliable protection from corrosion, even in extreme environments. You can modify the body and actuator for easy maintenance.

• Suitable for indoor and outdoor use
• Bifurcated gold contacts prevent friction damage from contact resistance
• LED (light-emitting diode) indicator for convenient monitoring of device state
• Versatile power source options, either via threaded conduit, pre-cabling or connector
• Mechanical life of at least 15 million cycles

• Construction industry
• Rail equipment
• Logistics stations

The core components are the switch body, actuator and roller lever. The switch body houses the electrical components that power the switch. The actuator is the mechanism that controls the direction of the roller lever. The roller lever is the rotating device that turns on its axis and makes physical contact with the target.
