The GLC series and GLD series of limit switches from Honeywell are a compact and versatile solution. The small size of the unit allows you to use them in applications and environments with a limited amount of space. These limit switches are constructed from rugged housing and can operate in severe environments.

• Control of two separate circuits is maintained by galvanically isolated contacts.

• These limit switches offer an excellent lifespan up to 10 million operations.

Suitable product applications include:

Although models have difference in actuator type, switch type and torque, the main difference between the GLC and GLD series is the housing material. GLC limit switches have a metal housing while GLD limit switches are constructed with plastic housing.

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.

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.

Open and close your circuits safely and reliably with this limit switch from Honeywell. It's designed for position sensing in machinery and has a roller plunger actuator for simple mechanical operation. The contacts are designed for snap-on connections, which allows you to install the component on your equipment simply and securely. The modular design of the switch also means that you can customise it easily, giving you plenty of flexibility in your electrical setup.

• Wide operating temperature range of -40°C to +85°C
• IP (ingress protection) 66 rating for protection against dust and low-pressure water jets
• Die-cast zinc housing capable of resisting heavy impact, oxidation and wear, for a long lifespan

• Lifts and escalators
• Transportation
• Conveyor belts

The switch's mechanical life is around 10 million operations, which ensures minimal maintenance and long service life.

The switch has NC (normally closed) contacts, which means they'll remain closed unless opened by the actuator.
