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.

Model GLCB07B is constructed from metal housing that meets Standard EN50047.

This model features a single pole, double throw (SPDT) snap action switch. It has a pin plunger at the top of the unit.

This limit switch features one normally closed (NC) and one normally open (NO) contact. This model features gold plated contacts that are suitable for handling low energy loads.

GLCA01A1B has a "-14 NPT conduit, ensuring that it is suitable for North American type cables.

This limit switch features operating torque of 16 N (or 3.6 lb) maximum.
