RFS - Side-Mounted Level Switch

Brand: KOBOLD Instruments, Inc

The KOBOLD RFS level switch is a cost-effective liquid level switch for mounting in the side walls of tanks.

The RFS is constructed in stainless steel for maximum media compatibility.

The straightforward design is distinguished by a small footprint, sturdy construction, and a high-capacity reed switch.

The stainless steel float contains a magnet that activates a sealed reed contact as the liquid level rises above or drops below the switch installation point.

The contact function may be selected as either normally open (N/O) or normally closed (N/C) by rotating the switch 180 degrees about its axis.

This simple design makes the RFS affordable and maintenance-free.
