Honeywell GLA Series Roller Lever Limit Switch, 2 NC/2 NO, IP67, Die Cast Zinc Housing, 600V ac, 6A

This limit switch is a rugged electromechanical device designed to detect position and actuate control circuits in industrial automation systems. It employs a roller lever actuator to convert mechanical movement into switching signals and is intended for side‑mounted installations where environmental sealing and Durable contacts are required.

• IP67 sealed enclosure prevents ingress in harsh environments
• Snap‑action contacts deliver fast, positive switching response
• 2NC/2NO contact configuration enables flexible circuit layouts
• Rated for 600V AC and 6A to handle high‑voltage switching
• Electrostatic epoxy‑coated zinc housing resists corrosion and wear
• Mechanical endurance of 15,000,000 operations supports long duty cycles

• Suitable for conveyor end‑of‑travel detection in factories
• Ideal for machine‑tool limit sensing and safety interlocks
• Used with heavy‑duty actuators in packaging equipment
• Can be used for position feedback in material‑handling systems

It uses an M20 cable entry to accommodate standard industrial conduits and glands.

It functions over an ambient range from −25°C up to a maximum of 85°C.

Termination is provided via the M20 entry with side‑orientated mounting to match panel or frame installations.

It is specified to switch up to 250V DC for appropriate DC control circuits.

UL/ UL listed for Canada

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.
