Honeywell Technologies GLA Series Roller Lever Limit Switch, 1 NC/1 NO, IP67, Die Cast Zinc Housing, 600V ac, 6A

This limit switch is a Compact mechanical position sensor designed for industrial control and automation tasks where precise actuation is required. It operates via a roller lever actuator and provides snap-action electrical changeover contacts suitable for monitoring movement or end-of-travel positions in machinery and equipment. The unit is housed in an electrostatic epoxy-coated zinc enclosure and has ingress protection suitable for demanding work environments.

• Snap-action contacts provide fast, reliable switching response
• 1NC and 1NO contact arrangement allows versatile circuit control
• Rated for 600V AC and 250V DC to handle varied supply voltages
• IP67 protection permits use in dusty and water-exposed locations
• Mechanical life of 15,000,000 operations supports long service cycles
• Operating range from -25 to 85°C maintains function across climates

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for limit sensing on robotic pick-and-place assemblies
• Used with motor starters to detect shaft or cam position
• Can be used for safety interlocks on access panels and guards
• Suitable for automated packaging machinery position feedback

The device uses an M20 Terminal entry to accommodate standard conduit fittings.

The roller lever is arranged for side mounting, allowing lateral actuation where space constraints exist.

The actuator operates with an operating torque equivalent to 0.33 Nm, providing defined force for consistent actuation.

It carries UL, CSA, CE and CCC approvals for use in applicable regulated installations.

It is not certified for hazardous-area classification and should not be specified where certified explosion protection is required.

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.
