Universal Hanging sensors can be used in the cases where there is not enough over head clearance to allow for the solid sensor rods we typically would like to see. Each sensor is set and secured with a conventional compression fitting to insure it stays at the correct level and is also color coded so it can be Identified all the way through to the Control panel.
It comes as a kit and part of the kit is a color coded terminal block in a NEMA4 enclosure. This enclosure is typically mounted within a few feet of the sensor head assembly.
