Honeywell BAF/DTF Series Limit Switch, 79mm Length, Die Cast Aluminium Housing - BAF1-2RQ9-LH

This limit switch is a Compact mechanical device designed to detect and control position or movement within industrial systems. It operates as a roller plunger actuator suitable for side mounting and offers electrical switching capability for both alternating and direct current environments. The robust housing and standard conduit entry make it applicable where a sealed enclosure and threaded cable connection are required.

Features and Benefits:

• Roller plunger actuator provides positive mechanical engagement and repeatability
• Die-cast aluminium housing offers sturdy protection in industrial settings
• Rated switching capacity supports 480V AC applications and 250V DC use
• Mechanical endurance of 10 million cycles reduces maintenance frequency
• Screw terminals enable secure and accessible wiring connections
• Conduit entry accommodates 1/2 in to 14 NPT fittings for cable routing

Applications

• Suitable for conveyor end-of-travel detection in manufacturing lines
• Ideal for position feedback on machine tools and presses
• Used for gate or door open/close monitoring in industrial enclosures
• Can be used for limit detection on material handling equipment

What temperature range can it operate within?

It functions across an ambient span from −32°C up to a maximum of 71°C, supporting cold-start conditions and elevated process environments.

How is the unit mounted and oriented mechanically?

It is designed for side-orientation mounting to Interface with mechanisms where lateral actuation is required.

Which approvals cover its electrical safety recognition?

The device carries CSA certification and is recognised under UL standards for industrial electrical components.

What ingress protection and enclosure classification does it have?

The enclosure is rated to IP3 and meets NEMA 1 criteria for non-hazardous indoor locations.

How large is the product footprint for tight installations?

The body measures 79mm in length, 35mm in width and 44mm in depth for Compact integration.
