Honeywell GLA Series Plunger Limit Switch, 1 NO/1 NC, IP67, Die Cast Zinc Housing, 600V ac

This limit switch is a mechanically operated plunger device designed to detect and interrupt motion in industrial systems. Built for demanding environments, it provides snap‑action contact switching with both normally open and normally closed outputs and is suitable for use where robust electrical isolation and environmental protection are required.

• IP67 enclosure ensures protection against dust and temporary immersion
• Snap‑action contacts handle up to 600V AC switching
• Two‑contact arrangement provides one NO and one NC contact
• Die‑cast zinc housing offers impact resistance and long service life
• Operating force of 16 N allows precise actuation response
• Mechanical endurance rated for 15 million cycles for extended operation

• Suitable for end‑of‑travel detection on automated conveyors
• Ideal for position sensing on industrial presses and machines
• Used with control panels requiring M20 conduit entry connections
• Can be used for safety interlocks in manufacturing cells
• Used for limit sensing in material‑handling equipment

It functions across a temperature span from −25 °C up to 85 °C, enabling use in many indoor and sheltered outdoor installations.

The unit accepts conduit via an M20 entry and offers screw‑type terminals for wiring the NO and NC contacts.

It is supplied with approvals from UL, CSA, CE and CCC to facilitate integration in regulated environments.

The switch is specified to withstand 15 million mechanical cycles, supporting high‑duty industrial applications.

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.
