Honeywell Technologies Roller Plunger Limit Switch SPDT IP3 Die Cast Aluminium Housing 480V AC 20A BAF1-2RQ9-LH

Honeywell Technologies BAF1-2RQ9-LH is a roller plunger limit switch designed for industrial automation and control applications requiring precise position or movement detection. This limit switch features an IP3 rated die cast aluminium housing providing robust environmental protection and mechanical durability. It supports Single Pole Double Throw (SPDT) snap action contacts rated for switching currents up to 20 amperes at 480 volts AC and 250 volts DC, making it suitable for both AC and DC electrical environments.

The device measures 101.6mm in length, 54.8mm in width, and 33mm in depth, allowing compact integration in confined spaces. It is engineered for side mounting with a roller plunger actuator that ensures positive mechanical engagement and repeatability. The limit switch has a mechanical life of 10 million cycles, substantially reducing the frequency of maintenance and replacement.

The BAF1-2RQ9-LH is equipped with screw terminal connections for secure electrical wiring and features conduit entry compatible with 1/2 inch to 14 NPT fittings to facilitate protected cable routing. Its operational temperature range of -32°C to 71°C supports harsh environmental conditions including cold starts and elevated ambient temperatures.

The product is CSA certified and recognized under UL standards, further assuring compliance with industrial electrical safety requirements. Hazardous area certification to NEMA 1 designates it appropriate for use in non-hazardous indoor locations. This limit switch is widely used in manufacturing lines for conveyor end-of-travel detection, machine tools and presses for position feedback, and gate or door monitoring in industrial enclosures, as well as material handling equipment for limit detection.
