Honeywell GLZ Series Roller Lever Limit Switch, IP67, Metal, Double Insulated Housing

This limit switch is a rugged electromechanical device designed to detect position changes in industrial systems using a roller lever actuator. It is built for use where a compact, upright-mounted switching solution is required and performs reliably across a broad temperature range and in harsh environments.

• Metal double-insulated housing provides enhanced electrical protection and durability
• Roller lever actuator enables positive mechanical engagement with moving parts
• Screw Terminal connections simplify secure wiring on-site
• Rated for continuous use between -40°C and 85°C supporting varied ambient conditions
• Mechanical endurance of 15,000,000 operations reduces maintenance interventions
• IP67 enclosure prevents ingress of dust and temporary immersion

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for door position sensing in heavy machinery safety systems
• Used for limit detection on packaging and material-handling equipment
• Can be used for position monitoring in robotics and automation cells

It meets standards from EN and IEC and holds RoHS, UL, CE, CCC and CSA approvals, enabling use where conformity marks are required.

The device is intended for upright installation

The roller lever provides low-friction contact and reliable actuation, helping achieve the specified mechanical life over numerous operations.

The enclosure is rated to IP67, offering protection against dust ingress and temporary immersion in water for wet-area installations.

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.
