Honeywell Technologies GLB Series Roller Lever Limit Switch, SPDT, IP67, Die Cast Zinc Epoxy Coated Housing, 600V ac,

This limit switch is a roller-lever actuated device designed for position sensing and control duties within industrial automation systems. Housed in a robust die-cast zinc enclosure, it is intended for environments where reliable actuation and electrical switching are required, accommodating standard conduit connections and screw-type wiring for integration into control circuits.

• SPDT snap-action contact provides positive switching at setpoints
• Rated for 10A switching current to handle moderate loads
• Accepts 20mm conduit entry for straightforward cable routing
• Mechanical endurance of 15 million cycles reduces replacement frequency
• IP67 ingress protection allows use in wet or dust-prone locations
• Operating range from -25°C to 85°C supports diverse environments

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for automated gate and door position feedback systems
• Used with motor starters for shaft limit monitoring in machinery
• Can be used for safety interlock sensing in processing equipment
• Used for material handling equipment position control in warehouses

It is specified to switch alternating voltages up to 600V, suitable for many industrial AC control circuits.

Termination is via screw terminals, providing secure, serviceable wiring for field installation.

The body is constructed from die-cast zinc, offering toughness and resistance to mechanical impact.

A roller-lever actuator converts linear or rotary contact into a snap action for Rapid contact transfer.

It holds recognised approvals from UL, CSA, CE and CCC for international deployment.

IEC/EN 60947-5-1
While IEC/EN 609747-1 covers general rules relating to low voltage switchgear and control gear, 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
GLB 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.
