MICRO SWITCH™ Global Limit Switches
GLA Series
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 .
VALUE TO CUSTOMERS
• Easy to install and maintain
• Rugged metal construction
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
FEATURES

pole galvanically (electrically) isolated (Zb)
• Normally closed contacts are positive opening , except
center neutral style
• Contact blocks are available as snap action or slow action
• Analog output available with side rotary actuator

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.
