Honeywell GLC Series Coil Spring Limit Switch, SPDT, IP66, Die Cast Zinc Epoxy Coated Housing, 240V ac, 10A

This limit switch provides mechanical position sensing and electrical switching for industrial control systems, using a coil-spring actuator and snap-action contacts to detect and change states in vertical installations. It is designed for environments requiring sealed enclosures and standard electrical switching capabilities, delivering dependable operation across a wide ambient temperature range.

• SPDT contact arrangement enabling single-pole double-throw switching for flexible control
• Snap-action contact type offering Rapid contact transition to reduce arcing
• 10A switching current at 240V AC suitable for common control circuits
• Rated for 250V DC switching to handle DC control loads where required
• Mechanical endurance of 15 million operations for long-term duty cycles
• Operating force 1.3 N minimises trigger effort for sensitive actuation

• Suitable for conveyor end-of-travel detection in automated lines
• Ideal for limit sensing on mechanical presses and stamping machines
• Used for position feedback in packaging and material handling equipment
• Can be used for safety interlocks in access panels and guards

The enclosure meets IP66 ingress protection, preventing dust ingress and resisting powerful water jets for external or washdown environments.

It accepts a 1/2 in to 14 NPT conduit entry for standard threaded conduit fittings and cable glands.

It operates reliably between -25°C and 85°C, accommodating low-temperature storage and elevated ambient working conditions.

The housing is constructed from die-cast zinc to provide a robust barrier against mechanical impacts and corrosion in industrial settings.

It carries recognised approvals including UL, RoHS, IEC, EN, CSA, CE and CCC for conformity with international standards.

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.
