Honeywell Technologies GLD Series Roller Plunger Limit Switch, DPST, IP66, Fibreglass Reinforced Thermoplastic Housing,

This limit switch provides precise mechanical position detection for industrial control systems, using a roller plunger actuator to register end-of-travel events. It is intended for integration into automated machinery and electrical panels where a compact, rugged switching element is required. The device offers environmental protection and straightforward electrical interfacing for robust field use.

• Dual-pole switching supports independent circuit control
• Slow-action contacts enable controlled make-and-break behaviour
• Rated for 10A switching current for common control loads
• Withstands temperatures from -40°C to 85°C for harsh sites
• Fibreglass reinforced thermoplastic housing for chemical resistance
• Achieves 10 million mechanical cycles for long service life

• Suitable for conveyor end-of-travel detection in factories
• Ideal for limit sensing on automated packaging equipment
• Used with industrial door and gate position monitoring systems
• Can be used for machine tool safety interlocks
• Suitable for electrical control panel signal inputs

It accepts PG13.5 conduit entry for sealed conduit or gland installations.

Terminals are screw-type allowing secure conductor attachment with common tooling.

The body meets IP66 ingress protection for dust-tight performance and powerful water jets.

It holds approvals from CE, UL, CSA and CCC for international application compliance.

UL/ UL listed for Canada

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.
