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.
