Honeywell GLA Series Limit Switch, 42mm Length, IP67 - GLAA20A2A


This limit switch is a Compact electromechanical device designed to detect and interrupt motion in industrial control systems. It provides snap-action contact switching and is intended for side-mounted installation where reliable position sensing is required in harsh or variable environments.

Features and Benefits:


• Snap-action contacts deliver fast switching response and reduced contact bounce
• 2NO/2NC arrangement allows flexible circuit configuration and redundancy
• Rated for 10A at 600V AC for robust load handling in control circuits
• Die-cast zinc housing offers mechanical robustness and long service life
• IP67 protection resists dust ingress and temporary immersion
• Operating force of 16N enables precise actuation and repeatable trips

Applications


• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for safety interlocks on material handling equipment
• Used for position sensing on pneumatic actuator strokes
• Can be used for limit detection in automated door mechanisms

What temperature range can it tolerate during operation?


It operates reliably between -25°C and 85°C, accommodating typical industrial ambient conditions.

How many mechanical cycles can it perform before fatigue?


The mechanism is specified for 15 million operations, supporting high-cycle automation tasks.

What conduit entry option is provided for wiring?


A 1/2 BSP (or 1/2 NPT adaptor) threaded entry is available for conduit connection and cable protection.

Which approvals indicate suitability for global installations?


It holds multiple approvals including UL, CE, RoHS, CSA and IEC-related certification marks.

Approvals

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.

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.
