Honeywell GLA Series Limit Switches
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.
Features:
• Both normally closed (NC) snap actions contacts and normally open (NO) slow action contacts are positive opening.
• An analog output is available with models featuring a side rotary actuator.
• Operating temperature between -40 °C and +85 °C.
• Able to withstand some washdowns, shock and vibration.
• Models with single pole double throw (SPDT) and two pole single throw (2NC and 2NO) contact blocks are galvanically isolated. With double pole double throw (DPDT) contact blocks, each pole is galvanically isolated.
• GLA limit switches feature bifurcated contacts.
Benefits:
• 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.
• These limit switches are incredibly easy to install and maintain.
• GLA limit switches are rugged and can be used indoors or outdoors. They are constructed from die-cast electrostatic epoxy coated zinc.
• You can have full confidence that these limit switches are a robust option. They are suitable for repeated use, with a mechanical lifespan of up to 15 million operations.
Product 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

Can I buy spare or replacement parts?
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.
Standards
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.

Warning
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.
Honeywell Replacement Basic Switch Body, For Use With GLS Series, SPDT Pole Configuration - GLZ Series - GLZ301
Replace a faulty limit switch in your application with this replacement basic switch body from Honeywell. Its SPDT (single pole double throw) configuration makes it an efficient choice as it allows you to control up to two circuits at once. Thanks to its snap-action mechanism, it reacts quickly to ensure rapid switching. This makes it ideal for use in sensitive automation applications.
Features & Benefits
• Compatible with various actuator heads such as plungers, levers and coil springs for versatile use
• Retaining screw allows you to easily fit it to the rest of your switch parts, ensuring simple installation and replacement
• Suitable for retrofitting, letting you reuse components of your switch to minimise waste

How does a limit switch work?
A limit switch has contacts that detect the presence of an object. When an object touches the contacts, the switch activates to open or close a circuit. This makes it ideal for measuring, positioning and transporting tasks.
