Honeywell Technologies GLD Series Plunger Limit Switch, SPDT, IP66, Fibreglass Reinforced Thermoplastic Housing, 240V

This limit switch is a Compact electromechanical device designed to detect physical position changes and transmit a corresponding electrical signal in industrial control systems. It is intended for robust on/off sensing within automation, electrical and mechanical setups where a snap-action response and environmental protection are required.

• Snap-action contacts provide Rapid switching response and reduced contact wear
• Single-pole double-throw arrangement allows versatile circuit control
• Rated switching current of 6A supports moderate load switching
• Withstands AC voltages up to 240V for common mains applications
• Mechanical endurance of 10 million cycles reduces replacement frequency

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for safety interlocks on access panels and enclosures
• Used with actuated valves for position feedback in fluid systems
• Can be used for limit detection on machine tool stages
• Suitable for integration into control cabinets requiring a screw-terminated switch

It employs a plunger actuator that provides direct-contact actuation, enabling straightforward alignment with moving parts and Compact mounting where linear motion is present.

The housing meets IP66 protection, offering complete dust exclusion and resistance to powerful water jets, suitable for harsh workshop environments.

The body is MADE from fibreglass-reinforced thermoplastic for mechanical strength and the electrical connections use screw terminals for secure, serviceable wiring.

It is rated to operate between -40 °C and 85 °C, allowing use in both low-temperature storage areas and warm equipment rooms.

A PG13.5 conduit entry is provided to accommodate standard gland fittings for protected cabling.

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.
