Frequently Asked Questions

What is the IFM SBN346 flow switch used for?

The IFM SBN346 is an adjustable set point flow switch used to monitor liquid flow in industrial piping systems. It is commonly applied in cooling circuits, lubrication systems, and process control to detect flow or no-flow conditions, triggering a PNP signal when flow reaches 1.32 gpm.

What are the specifications of the IFM SBN346?

The IFM SBN346 is a piston-type flow switch with an aluminum body, 1-inch NPT connection, and adjustable set point. It has a normally open switch position, 100 mA DC contact rating, PNP output, and a fixed flow range of 1.32 gpm. The manufacturer part number is SBN346.

Where to buy the IFM SBN346 worldwide?

3G Electric supplies the IFM SBN346 flow switch worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this adjustable set point flow switch to any country.

How to install the IFM SBN346 flow switch?

Install the IFM SBN346 in a horizontal or vertical pipe section with full flow. Ensure the arrow on the body aligns with flow direction. Use thread sealant on the 1-inch NPT connection and tighten to avoid leaks. Wire the PNP output to a 24 VDC supply; the normally open contact closes at 1.32 gpm.
