Honeywell BAF Series Limit Switch, 20A Switching Current, 480V Switching AC Voltage - BAF1-2RN-RH

This limit switch provides mechanical position detection for industrial control and safety systems, using a plunger actuator for direct contact sensing in vertical mounting arrangements. It is built with a robust die-cast aluminium enclosure and supports field wiring via a 1/2 in NPT conduit entry, making it suitable for integration into automated machinery and electrical panels where a compact, rugged switch is required.

Features and Benefits:

• SPDT snap-action contacts for fast, positive switching action
• Rated switching current 20A for high-load circuit control
• Accepts up to 480V AC or 250V DC for versatile supply compatibility
• Operating force 11.2 N enables repeatable actuation sensitivity
• Works across -32°C to 71°C for extended ambient range
• CSA, UL and RoHS approvals for recognised industrial standards

Applications

• Suitable for limit detection on automated conveyors and presses
• Ideal for end-of-travel sensing on actuated valves and cylinders
• Used with motor starters for overtravel protection in machinery
• Can be used for position feedback in packaging equipment

How should it be oriented during installation for correct actuation?

It is designed for vertical mounting to ensure the plunger operates within intended travel and maintains consistent actuation force.

What environmental protection does the enclosure provide on-site?

The body is die-cast aluminium offering mechanical robustness and an IP-rated design suitable for industrial atmospheres where ingress resistance is required.

Which wiring method is compatible with existing conduit runs?

The switch accommodates a 1/2 in NPT conduit entry allowing straightforward connection to standard conduit systems and gland fittings.

How does the contact arrangement affect control logic integration?

The single-pole double-throw contact configuration provides both normally open and normally closed outputs so it can be wired for either make-or-break signalling in control circuits.

Approvals

UL, CSA.
