Honeywell GLA Series Plunger Limit Switch, 1 NO/1 NC (SPDT), IP67, Die Cast Zinc Housing, 600V ac, 6A

This limit switch provides position sensing and end-of-travel detection for industrial automation and machinery control. Fitted with a plunger actuator and a snap‑action contact mechanism, it is designed for installation where robust switching performance and ingress protection are required. The enclosure is constructed from die‑cast zinc and intended for use in demanding electrical and mechanical environments.

• IP67 rated enclosure prevents dust ingress and temporary immersion
• Snap‑action SPDT contacts deliver decisive switching performance
• Electrical switching up to 600V AC and 6 A supports high‑voltage circuits
• Mechanical endurance rated for 15 million cycles reduces maintenance frequency
• Operating temperature range from -25 to 85°C suits varied climate conditions
• PG13.5 conduit entry enables secure cable connection in wet areas

• Suitable for conveyor end‑of‑travel detection in manufacturing lines
• Ideal for safety interlocks on industrial machinery panels
• Used for position feedback in automated assembly equipment
• Can be used for limit sensing in material handling systems
• Suitable for use in electrical switchgear control circuits

It uses a single‑pole double‑throw contact set with one normally open and one normally closed contact, allowing both make‑and‑break signalling from a single actuator for flexible control logic.

The plunger actuator provides axial actuation and is suitable where a linear striker or cam engages the switch, simplifying alignment on shafts or sliding guides.

The unit carries UL, CSA, CE and CCC recognitions, indicating it meets multiple international safety and performance standards for electrical devices.

The die‑cast zinc body offers solid mechanical protection against impacts and contributes to reliable operation in environments with physical handling and vibration.

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.
