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 .

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

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.

FEATURES

• Designed to EN50041 standard, 30 mm x 60 mm mounting

• Available as a standard body or plug-in body with same

footprint

• Wide range of actuator heads and levers

• Side rotary switches factory set for CW and CCW actuation;

ﬁeld adjustable for CW only or CCW only

• Certiﬁed for global applications; UL/CSA (Americas/Canada),

CE (Europe), CCC (Asia-Paciﬁc)

• Conforms to IEC/EN 60947-5-1, EN45545-2 (GLA/GLF Series)

• Sealed to IP67 and NEMA/UL 1, 4, 12, and 13

• Operating temperatures as low as -40 °C to 85 °C

[-40 °F to 185 °F]

• Multiple connectivity options to meet most applications: four

different threaded conduits, micro-change connectors, mini-

change connectors, Deutsch style 4-pin connector

• One or two LED indicators available in switch body

• Single pole double throw, two pole single throw contact blocks

(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)

• 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

• Mechanical life up to 15 million operations

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

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

these regions is available upon request.

MICRO SWITCH Global Limit Switches, GLA Series APPLICATION INFORMATION Figure 14. Actuation Adjustment Side Rotary Assemblies The side rotary assemblies incorporate a feature for adjusting the free position of the side rotary lever. The EN 50041 body style allows infinite adjustment and reclamp. See the following diagrams for details of the mechanism in each case. Figure 12. Standard EN 50041 Body Style REPLACEMENT INSTRUCTIONS All levers for side rotary assemblies are available as replacment parts.
