Honeywell GLC Series Adjustable Roller Lever Limit Switch, 1 NC/1 NO, IP66, Die Cast Zinc Housing, 240V ac, 6A

This limit switch is a Compact electromechanical device designed to detect position changes and actuate electrical circuits in industrial systems. It is intended for use where robust, Rapid switching is required, offering environmental protection for installations exposed to dust and water ingress. The unit incorporates a rolling actuator mechanism to translate mechanical movement into a switching action suitable for control, safety interlock and monitoring functions.

• Snap-action contacts deliver quick state changes for precise control
• 1NC and 1NO arrangement supports versatile circuit logic
• Rated for 240V AC and 250V DC to handle common supply types
• Operational temperature range from -40 to 85°C for harsh conditions
• Mechanical endurance of 10,000,000 cycles reduces replacement frequency
• IP66 enclosure with electrostatic epoxy-coated zinc resists ingress

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for door or hatch position monitoring in plant equipment
• Used with actuated valves for position feedback in process systems
• Can be used for safety interlocks on packaging machinery
• Suitable for limit sensing on material handling gantries

The device accepts a PG13.5 conduit entry to simplify secure wiring and gland fitting.

The unit employs an adjustable roller lever actuator allowing alignment to the motion profile without altering the housing.

Contacts operate with a snap-action mechanism that ensures a Rapid transition between states to minimise arcing and contact wear.

The housing uses zinc with an electrostatic epoxy coating to provide corrosion resistance and a robust external finish.

The product carries CCC, CE, CSA and UL approvals, indicating conformity with multiple regional 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.
