Honeywell Technologies GLD Series Roller Lever Limit Switch, SPDT, IP66, Fibreglass Reinforced Thermoplastic Housing,

This limit switch provides a compact, industrial-grade mechanical position sensing solution for automation and control systems. It employs a roller lever actuator to detect motion and transmit a discrete switching signal, designed for use in demanding environments where robust enclosure protection and defined switching behaviour are required.

• SPDT snap-action contact offers clear single-pole changeover switching
• Rated for 10A enables handling of significant control currents
• IP66 fibreglass-reinforced enclosure resists dust and powerful jets
• Mechanical endurance of 10 million cycles supports long service intervals
• Operating range from −40 °C to 85 °C suits extreme temperature conditions
• Actuation force 16 N provides predictable trigger response under load

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for safety interlocks on industrial guarding systems
• Used with motor starters for position feedback in hoists and lifts
• Can be used for limit detection on automation pick-and-place units
• Used for end-stop sensing in material handling equipment

The unit accepts a 1/2 in to 14 NPT conduit entry for standard threaded conduit connections.

The single-pole double-throw configuration allows selection between normally closed and normally open circuits for flexible control logic.

The contacts are specified for switching at 240V AC and up to 250V DC to accommodate typical control and signal voltages.

The enclosure is MADE from fibreglass-reinforced thermoplastic, providing mechanical resilience and corrosion resistance in harsh settings.

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.
