Honeywell Technologies GLB Series Roller Lever Limit Switch, 1 NO/1 NC, IP67, Die Cast Zinc Epoxy Coated Housing, 600V

This limit switch is a rugged industrial device designed to detect mechanical position changes and provide discrete electrical switching in automation and control systems. It features a roller lever actuator and a snap-action contact mechanism to deliver precise switching operations across electrical circuits in demanding environments.

• Die-cast zinc housing for robust mechanical protection
• IP67 ingress rating enabling operation in wet or dusty conditions
• 1NO/1NC contacts handling up to 10A switching current
• 600V AC and 250V DC switching capacity for varied supply systems
• Operating temperature range from -25°C to 85°C for wide thermal tolerance
• Mechanical life rated to 15 million cycles for extended duty

• Suitable for conveyor end-of-travel detection in factories
• Ideal for limit sensing on industrial presses and cutters
• Used with automated gantries for position feedback
• Can be used for safety interlocks on access panels
• Suitable for packaging machinery repeatable position control

The device accepts a PG13.5 conduit entry and uses an M20 Terminal arrangement for electrical connection.

The roller lever actuator operates silvered snap-action contacts designed to maintain switching precision through high-frequency mechanical cycles.

The unit carries CE, UL, CSA and CCC approvals suitable for multiple regional compliance requirements.

The operating torque is specified as 0.33 Nm, which informs mounting and lever alignment to ensure reliable actuation.

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.
