Honeywell GLC Series Roller Plunger Limit Switch, SPDT, IP66, Die Cast Zinc Housing, 240V ac, 6A

This limit switch provides precise position detection for industrial automation and control systems, using a roller plunger actuator to convert mechanical movement into an electrical signal. It is suited to demanding environments where a compact, enclosed switching device is required and supports standard conduit attachment for wiring.

• SPDT snap-action contact reduces contact bounce for reliable switching
• Mechanical endurance of 10 million cycles enables long service intervals
• Switching capacity 6A at 240V AC for common control circuits
• IP66 enclosure rating protects against dust and powerful water jets
• Operating temperature range −40 to 85 °C maintains performance across climates
• PG13.5 conduit entry simplifies secure cable installation

• Suitable for end-of-travel detection on conveyor lines
• Ideal for machine-tool position sensing in production cells
• Used with motor starters for safety interlock feedback
• Can be used for door and access control in hazardous areas
• Suitable for assembly automation where robust actuation is required

It employs a single-pole double-throw snap-action contact that switches rapidly between circuits, providing a clear changeover suitable for control logic and interlock circuits.

The housing is formed from die-cast zinc, offering mechanical strength and resistance to impact in industrial settings.

The body is designed for space-conscious installations with a low profile and narrow footprint to fit confined mounting locations.

It carries recognised safety approvals, indicating conformity with multiple international electrical and safety standards.

The actuator requires an operating force of 16 N to engage the switching mechanism.

GLC and GLD limit switches are not safety devices. They should be not used as emergency stop or safety devices. They must not be used in applications where personal injury could occur as a result of product failure.

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.
