Honeywell GLAB01C

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
Apertures and doors
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 Limit Switch, Top Roller Plunger, Snap-Action Contacts - GLA Series - GLAB01C
Detect objects in your industrial equipment using this limit switch from Honeywell. When its roller plunger actuator makes physical contact with a component, it triggers the contacts to open or close. The die-cast zinc housing offers resistance to corrosion and wear for long-lasting use. A wide operating temperature range between -25°C and +85°C means you can use this switch in demanding environments.
Features & Benefits
Tough stainless steel roller plunger is resistant to impact and corrosion
Silver alloy contacts have high electrical conductivity and resistance to corrosion for reliable switching
Rated impulse withstand voltage of 2500V for protection against powerful surges
Applications
Safety systems
Textile production
Transportation industry
Construction equipment
How durable is this limit switch?
This limit switch has a robust mechanical service life of 15 million cycles, so it won't need frequent replacement.
