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

This limit switch provides mechanical position detection and circuit switching for industrial automation and machinery control. Housed in a robust die‑cast zinc enclosure with protection against dust and water ingress, it is intended for side‑mounted use where a lever‑actuated contact change is required. The device supports both AC and DC switching duties and is specified for demanding operational environments.

• Snap‑action contacts delivering quick, positive switching
• Single changeover contact offering flexible control logic
• Rated for 10A enabling substantial load handling
• Withstands switching at 600V AC for high‑voltage circuits
• Operates down to −25 °C and up to 85 °C for temperature resilience
• Mechanical life of 15 million operations for extended duty

• Suitable for conveyor end‑of‑travel detection in factories
• Ideal for machine tool limit sensing in metalworking
• Used with automated Gates and door interlocks in facilities
• Can be used for position feedback in packaging equipment
• Used for safety cut‑out detection on industrial presses

The unit is designed for side mounting to align the lever with the actuated mechanism and secure conduit entry positioning.

The device accepts 0.5 to 14 NPT conduit entries to match common industrial conduit sizes and fittings.

It provides one normally open and one normally closed snap‑action contact, permitting use for both make and break signalling in control circuits.

It conforms to several industry standards and approvals, including UL, IEC, EN, CSA, RoHS, CE and CCC.

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.
