FAQ

This float switch has four wires. How is it wired?

The four wires typically correspond to a protective earth (green/yellow) and a changeover contact: common, normally open (NO), and normally closed (NC). This allows the switch to be used for either filling (pump on when level is low) or emptying (pump on when level is high) applications. Always verify wiring with a multimeter before installation.

What does the IP68 rating mean for this float switch?

The IP68 rating indicates the highest level of protection against dust and water ingress. The ‘6’ means it is completely dust-tight. The ‘8’ signifies it is suitable for continuous immersion in water under conditions specified by the manufacturer, making it ideal for use in tanks, wells, and sumps.

What is the switching differential (hysteresis) of the PS-E?

The switching differential is the difference in liquid level between the switch-on and switch-off points. For a pear-shaped float switch like the EHZ PS-E, this is determined by the free length of the cable from the suspension point to the float. A longer free cable results in a larger differential. For precise values, consult the manufacturer’s technical datasheet.
