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.

Choose this high-spec limit switch from Honeywell for assured operation in challenging environments. Its rugged epoxy-coated, die-cast zinc housing is corrosion-resistant and can handle shocks and washdowns. The unit works by making or breaking an electrical connection when an object makes contact with the roller lever actuator. The NC (normally closed) contacts are direct-acting and guaranteed to open when activated. Because they're galvanically isolated, two separate circuits can be maintained.

• High-performing and durable with up to 10 million operations
• Wide operating temperature range of -40°C to +85°C makes this switch suitable for both very hot and extremely cold environments
• Bodies, contact blocks and heads can all be adjusted for easy customisation
• Meets EN 50047 mounting standards and EN/IEC worldwide electrical standards

• Textiles manufacture
• Construction equipment
• Commercial appliances

This Honeywell limit switch comes with a size 14 NPT (national pipe thread) opening for side mounting that's suitable for standardised conduit fixings. It can also be rotated in 90° increments to suit your installation needs. A removable contact block and clearly marked, easy-to-access wiring terminals make installation straightforward.
