Honeywell GLB Series Rod Limit Switch, 1 NO/1 NC, IP67, Die Cast Zinc Housing, 600V ac, 10A

This limit switch provides position detection for industrial automation and control systems, offering a rugged control input for mechanical processes. It is designed for straightforward installation in demanding environments where a rod-type actuator is required, delivering snap-action electrical signalling for machine control and safety interlocks.

• Electrostatic epoxy-coated zinc housing for corrosion resistance and longevity
• 1 NO 1 NC snap-action contacts rated for 600V and 10 A for heavy-duty switching
• IP67 ingress protection enabling use in wet and dusty conditions
• Mechanical life of 15,000,000 operations for sustained cycling applications
• Operating temperature range −25 to 85 °C for wide environmental tolerance
• Low operating torque of 0.33 N·m for reduced actuation force requirements

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for plunger- or cam-actuated machine safety interlocks
• Used with packaging equipment for repetitive position sensing
• Can be used for valve position feedback in process plants
• Used for indexing control on automated assembly machinery

The enclosure accommodates an M20 conduit entry to suit standard industrial trunking.

The rod actuator provides linear contact with moving parts and permits side or end actuation in standard mounting orientations.

The body is MADE from zinc with an electrostatic epoxy coating to reduce corrosion and surface wear.

It is approved to CE, UL, CSA and CCC standards for international installation requirements.

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.
