Honeywell GXA Series Limit Switch, IP66, 0.33Nm Operating Force - GXA51A2B


This limit switch is a Compact side-mounted rotary device designed to provide discrete position detection in industrial control systems. It operates via a lateral rotary actuator and delivers Rapid electrical changeover using a snap-action contact mechanism. The enclosure is MADE from die-cast zinc and sealed to an ingress protection rating suitable for demanding environments. The unit is intended for use where robust switching, clear on/off signals and compliance with recognised standards are required.

Features and Benefits:


• Snap-action contacts provide fast, positive switching response
• ATEX certification permits use in specified hazardous atmospheres
• IP66 enclosure prevents dust ingress and powerful water jets
• Mechanical life rated at 2,000,000 ops for long service intervals
• Switching capability of 250V at 4 A supports common control circuits
• Operating torque of 0.33 N·m enables precise actuation force control

Applications


• Suitable for position sensing on industrial valves and actuators
• Ideal for conveyor end-of-travel detection in manufacturing lines
• Used for limit monitoring on gate and door control mechanisms
• Can be used for safety interlocks in hazardous-area installations

What Terminal arrangement does it use for wiring connections?


Electrical connections are provided via a cable-style Terminal suited to fixed wiring installations.

What temperature conditions will it tolerate during operation?


It functions across a tested ambient range from -20 °C up to 75 °C for typical industrial environments.

How is mounting orientation accommodated on machinery?


It is designed for side mounting to integrate with shaft- or lever-driven actuators where lateral engagement is required.

Which approvals indicate suitability for European installations?


It conforms to recognised CE/EN/IEC standards applicable to electromechanical switching devices.
