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

This limit switch is a Compact mechanical position sensor designed for industrial automation and control systems. It detects actuations via a metal roller actuator and is intended for installation in harsh environments where a sealed enclosure and reliable switching are required. The device connects to control circuitry via screw terminals and accepts a standard PG13.5 conduit entry for wiring.

• Metal roller actuator reduces wear and enables consistent actuation force
• DPST slow-action contacts provide controlled switching behaviour under load
• Rated switching current 6A to handle moderate control circuits
• Operational temperature range -40 to 85 °C for wide thermal conditions
• Fibreglass-reinforced thermoplastic housing delivers impact and corrosion resistance
• Mechanical endurance rated to 10 000 000 cycles for long service intervals

• Suitable for end-of-travel detection on conveyor equipment
• Ideal for limit sensing on industrial valves and actuators
• Used with motor starters for safety interlock switching
• Can be used for position feedback in packaging machinery
• Used for control panel input via PG13.5 conduit installations

It holds internationally recognised approvals from CSA, CE, UL and CCC, enabling use where those standards are required.

The enclosure provides a PG13.5 conduit entry for cable glands and internal screw terminals for secure conductor connection.

The contacts are specified for switching up to 240V AC at rated current and up to 250V DC for DC loads.

The housing material and sealing achieve an IP66 rating, offering protection against dust ingress and powerful water jets.

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.
