Honeywell GLC Series Plunger Limit Switch, SPDT, IP66, Die Cast Zinc Epoxy Coated Housing, 240V ac, 6A

This limit switch is a Compact mechanical device that detects and signals the position of moving parts in industrial systems. It employs a plunger actuator and snap-action contacts to provide fast switching for control and safety circuits. The housing is constructed from die-cast zinc and the unit is engineered for use in demanding environments where ingress protection and a wide operating temperature range are required.

• SPDT snap-action contact provides Rapid state change and clear signalling
• IP66 enclosure keeps internal components protected from dust and powerful water jets
• Operating force of 16 N ensures consistent actuation under variable loads
• Electrical switching capacity of 6A at 240V AC supports common control circuits
• Mechanical endurance rated to 10 million cycles minimises service interventions
• Conduit entry PG13.5 enables secure cable gland installation

• Suitable for limit detection on conveyor endstops and Gates
• Ideal for position feedback in automated assembly equipment
• Used with hydraulic cylinders for stroke limit monitoring
• Can be used for safety interlocks on machine guards
• Suitable for control panels in outdoor process installations

It operates reliably from −40 °C up to 85 °C, permitting use in both cold storage and elevated-heat enclosures.

The single-pole double-throw contact provides both normally open and normally closed outputs for direct connection to control relays or PLC input modules.

The enclosure is die-cast zinc and the unit carries CCC, CE, CSA and UL recognitions for conformity to multiple regional standards.

It is rated for switching up to 250V DC, allowing integration with common DC control supplies.

UL/ UL listed for Canada

GLC and GLD limit switches are not safety devices. They should be not used as emergency stop or safety devices. They must not be used in applications where personal injury could occur as a result of product failure.

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.
