Honeywell Technologies BX Series Roller Lever Limit Switch, Aluminium Housing, SPDT, IP67, 600V AC, 6A BX4A3K-1A

Honeywell Technologies BX4A3K-1A Roller Lever Limit Switch is a durable industrial electromechanical device designed for precise detection and interruption of mechanical motion in automated systems. Constructed with aluminium housing, it provides robust protection rated at IP67, making it suitable for use in harsh industrial and hazardous environments.

Featuring a single-pole double-throw (SPDT) snap-action contact, this switch supports a switching current of 6 amps at 600 volts AC, delivering reliable electrical performance. It operates efficiently over an extended temperature range from −40°C up to +70°C, ensuring stable operation in extreme conditions commonly found in manufacturing, process plants, and heavy machinery.

The roller lever actuator offers mechanical actuation with a low operating force of 0.45 N·m, facilitating precise and consistent triggering. Its secure M20 terminal entry allows for safe cable gland or conduit installation in complex industrial wiring setups.

The switch carries important hazardous area certifications including ATEX and IECEx, confirming its compliance for use in explosive atmospheres when installed per regulations. This makes it ideal for safety interlock applications on industrial doors, valve position sensing, conveyor end-of-travel detection, and actuator feedback in heavy-duty equipment.

Compact in size with dimensions measuring 146.05mm in length, 50.8mm in width, and 72.9mm in depth, the switch is easy to mount where space restrictions exist. Its aluminium construction reduces the risk of corrosion, extending product life in demanding environments.

Single-pole double-throw snap-action contact for swift load switching. 600V AC switching capacity rated at 6 amps. IP67 ingress protection for wet and dusty settings. Robust aluminium housing for corrosion resistance. Wide temperature operation from −40°C to +70°C.
