Honeywell GLC Series Plunger Limit Switch, 2 NC, IP66, Die Cast Zinc Epoxy Coated Housing, 600V ac, 10A

This limit switch provides a compact, mechanical method for detecting position changes in industrial systems and actuates control circuits when a plunger is engaged. It is designed for use in harsh environments and integrates a slow-action contact arrangement suitable for switching both AC and DC loads, offering compatibility with electrical control panels and machinery interfaces.

• Die-cast zinc housing giving enhanced environmental protection
• IP66 rating resisting dust ingress and powerful water jets
• Two normally closed contacts supporting 10A switching current
• Rated for 600V AC and 250V DC switching capability
• Mechanical endurance rated for 10 million cycles
• Operating force 13N enabling consistent actuation behaviour

• Suitable for industrial conveyor position detection
• Ideal for limit sensing on automated assembly equipment
• Used with motor control panels for safety interlocks
• Can be used for end-of-travel detection on linear actuators
• Used for gate and door position feedback in factories

It functions across a broad span from -40°C up to 85°C for both cold and hot workplace conditions.

The device accepts conduit via an M20 entry to simplify cable feed and gland installation.

The switch is specified to withstand 10 million mechanical cycles before end of life under rated conditions.

It meets multiple certification standards including CE, UL, CSA and CCC for diverse market acceptance.

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.
