Honeywell GLA Series Plunger Limit Switch, 1 NC/1 NO, IP67, Die Cast Zinc Housing, 600V ac, 6A

This limit switch is a plunger-operated device designed for position sensing and circuit interruption in industrial control systems. It provides snap-action contacts for Rapid switching and is intended for use in automation, electrical and mechanical installations where a robust, sealed actuator is required.

• IP67 rating ensures protection in wet and dusty environments
• Snap-action contacts deliver quick, reliable switching at load
• 600V AC switching capability supports high-voltage control circuits
• 6A current rating handles moderate control and signalling loads
• Operating temperature range down to -25°C and up to 85°C allows wide thermal use
• Mechanical endurance rated at 15,000,000 operations reduces maintenance frequency

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for machine tool limit sensing in metalworking facilities
• Used with motor starters for safety interlock feedback
• Can be used for position feedback in packaging equipment
• Suitable for gate and barrier open/close monitoring in access control

It accepts an M20 conduit entry to accommodate standard industrial cabling.

Terminals provide a single normally closed and a single normally open contact for flexible control logic.

The enclosure is finished with an electrostatic epoxy-coated zinc treatment for enhanced surface protection.

It carries approvals from UL, CSA, CE and CCC for international acceptance.

The plunger requires an operating force of 16 N to activate the switching mechanism.

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.
