Honeywell Technologies GLA Series Roller Lever Limit Switch, 1 NO/1 NC, IP67, Die Cast Zinc Housing, 600V ac

This limit switch provides mechanical position detection for industrial control systems, using a roller lever actuator to register movement and trigger control circuits. It is designed for demanding environments where sealed enclosure protection and defined contact switching are required, supporting both alternating and direct current control tasks.

• Roller lever actuator delivers reliable actuation with low torque
• Snap‑action contacts enable Rapid make/break switching at voltages specified
• IP67 sealed enclosure protects internals from dust and immersion
• Electrostatic epoxy‑coated zinc housing resists corrosion in harsh sites
• Terminal configured for M20 conduit ensures secure cable entry
• Rated for heavy‑duty life of 15,000,000 operations for long service

• Suitable for conveyor end‑of‑travel detection in factories
• Ideal for machine‑tool limit sensing in automated production
• Used for safety interlocks on industrial doors and guards
• Can be used for position feedback in material‑handling systems

It provides one normally open and one normally closed contact with snap‑action switching suitable for AC up to 600V and DC up to 250 V, enabling both make and break signalling in control circuits.

The unit is rated to operate from −25 °C up to 85 °C, allowing use in a wide range of indoor and sheltered outdoor industrial locations.

Mechanical endurance is specified as 15,000,000 operations, making it appropriate for high‑cycle installations requiring extended service life.

It carries multiple standards approvals including CE, UL, CSA and CCC to meet regional conformity requirements.

Use the provided M20 conduit entry for secure cable installation and select compatible glands to maintain the IP67 enclosure integrity.

GLA limit switches have not been designed as emergency stop or safety devices. They must not be used in applications where personal injury could occur as a result of the products failing.

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.
