Honeywell GLA Series Rod Limit Switch, 1 NO/1 NC (SPDT), IP67, Die Cast Zinc Epoxy Coated Housing, 600V ac, 6A

This limit switch is a Compact mechanical device designed to detect and control movement in industrial automation systems. It provides a Durable sensing solution for electrical and mechanical environments, combining a rod-style actuator with a robust enclosure to maintain operation across a wide temperature range and in challenging installation conditions.

• IP67-rated enclosure provides dustproof and waterproof protection
• Die-cast zinc housing resists mechanical impact and wear
• Snap-action contacts deliver fast, repeatable switching operation
• 15 million cycle mechanical life reduces maintenance frequency
• Switching capability up to 600V and 6A supports heavy-duty loads
• Threaded conduit entry simplifies secure cable routing

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for position sensing on industrial actuators and linkages
• Used with motor controls for limit and safety interlocks
• Can be used for gate and barrier position monitoring in facilities
• Suitable for harsh-environment machinery requiring sealed switches

The rod actuator responds to linear contact pressure and is designed to operate with an actuation force of 9.5 N, enabling consistent engagement with mechanical linkages.

It operates between -25 °C and 85 °C, allowing use in both cold storage and elevated-temperature process areas while maintaining contact function.

The switch uses a single-pole double-throw configuration with one normally open and one normally closed contact, permitting either make-before-break or break-before-make control schemes depending on wiring.

Cables are routed through a threaded conduit entry to ensure a mechanically secure and sealed connection compatible with industrial conduit fittings.

UL/ UL listed for Canada

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.

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.
