Honeywell Technologies GLZ Series Roller Plunger Limit Switch, IP67, Double Insulated, Metal Housing, 6A

This limit switch is a rugged position-sensing device designed for industrial control and safety applications. It employs a roller plunger actuator to detect mechanical movement and provides a wired switching output via screw terminals. The unit is built for demanding environments and long service cycles, making it suitable for automation and machinery control contexts.

• IP67-rated enclosure provides dust-tight and waterproof protection
• Rated switching current of 6A supports common industrial loads
• Operates from −40°C to 85°C for broad temperature use
• Mechanical life 15,000,000 operations for extended duty cycles
• Double-insulated metal housing reduces risk of electrical faults
• Screw Terminal arrangement allows secure field wiring

• Suitable for end-of-travel detection on conveyors and loaders
• Ideal for machine interlocks in manufacturing cells
• Used with actuator arms for automated assembly lines
• Can be used for position sensing in packaging machinery
• Suitable for safety stops on material-handling equipment

The switch is intended for bottom mounting

The component holds multiple international approvals, allowing integration in systems requiring recognised safety and conformity marks.

Wiring is completed via screw terminals that accept stranded or solid conductors and permit firm clamping for vibration-prone environments.

The unit functions across a wide thermal span from −40°C up to a maximum of 85°C, suitable for cold stores through heated plant areas.

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.
