Honeywell GLA Series Plunger Limit Switch, 2NO/2NC, IP67, DPDT, Die Cast Zinc Housing, 600V ac Max, 10A Max

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.

Model GLAB20D is a double pole, double throw (DPDT) snap action limit switch. It features two normally open (NO) and two normally closed (NC) contacts.

This limit switch has a 19 x 8 mm roller lever at the top of the unit. You can use roller lever actuator limit switches in applications where the cam laterally passes the switch.

GLAB20D has a PG 13.5 conduit, ensuring that it is suitable for European type cables.

Fitted with silver contacts as standard, this model is perfect for your power switching applications.

• IP67 rating for protection against dust and submersion in 1m of water for up to 30 minutes
• Die-cast zinc housing material for resistance to corrosion and impact

• Aerial and boom lifts
• Commercial and industrial automated doors
• Material handling and machining tools

This limit switch has a long lifespan of up to 15 million mechanical operations, so it will last a long time and won't need frequent replacement.
