Thermo Flo AT1x Liquid Flow Switch with CJB

This general-purpose liquid or gas flow switch package provides a low flow detection solution for pump or process protection with a 1A relay interface for remote devices such as a PLC, SCADA, or alarm.

The short sensor is intended for use in pipe or ducting from 1/2″ to 11/2″; the long sensor is applied in 2″ and up. The Switch Pro CJB flow switch is broadly selected for low or no-flow applications; just specify the appropriate sensor technology, length, and material.

The NEMA 4X enclosure is made of UL approved fire-retardant PP and features a 300° swivel base for easy conduit alignment. The power and switch terminals are pre-wired to the terminal strip.
