(1NC/1NO, 2NC, 2NO) are galvanically (electrically) isolated
(Zb) and designed with bifurcated contacts
• Two pole double throw contact block (2NC/2NO) has each
pole galvanically (electrically) isolated (Zb)

• Analog output available with side rotary actuator
• Mechanical life up to 15 million operations
DESCRIPTION
Honeywell’s MICRO SWITCH GLA Limit Switch Series is
designed to global EN50041 standards and well suited for
worldwide applications. The modular design (heads/actuators,
bodies, and contact blocks) of the limit switch allows for rapid
response to meet customer applications. The rugged die-cast
metal housing of the switch is ideal for indoor and outdoor
applications where a degree of IP or NEMA enclosure sealing is
required. Normally closed snap-action contacts and normally
closed slow-action contacts are positive opening
.
DIFFERENTIATION
• Side rotary actuator incorporates dual bearing design which
prevents side loading during operation
• Removable contact block allows for ease of wiring
• Modular design of limit switch (heads/actuators, bodies, and
contact blocks) allows for rapid customization and delivery
• Optional 1 LED or 2 LED pilot lights in limit switch front
cover to indicate voltage present to switch and/or switch
actuated
• Specialty contact options, sequential (2-step style) action,
and center neutral action
POTENTIAL APPLICATIONS
Aerial lifts, boom lifts
Automotive assembly lines and machining centers
Agriculture equipment
Conveyors
Doors and apertures
Material handling
Machine tools
Railroad locomotives and railroad signaling equipment
Transportation hubs
Valves
PORTFOLIO
The GLA Limit Switch Series with standard or plug-in
housings (EN50041 design, with 30 mm x 60 mm mounting)
complement the smaller GLC Series, GLD Series and GLE
Series (EN50047 design, with 20 mm to 22 mm mounting).
The GLA Series is part of the MICRO SWITCH Limit Switch
Series that includes the
HDLS Series (Heavy Duty Limit
Switch)
and
General Purpose Limit Switch (LS) Series.
VALUE TO CUSTOMERS
• Easy to install and maintain
• Rugged metal construction
CCC certification is not available on the GL Series Switches sold
within Europe, Middle East, and Africa. Option for CCC certification in
