power from the circuit it is wired into and not an external power source. An example would be a 4-20ma circuit from a controller. There will be positive terminal for the circuit to enter the sensor and a negative terminal to leave the circuit. The sensor actually becomes part of the 4-20ma power loop. In a traditional power source, you would need a positive and negative connection as well as a &quot;switch leg&quot; connection.<br /><br />Thank you for using Grainger Ask &amp; Answer</div><div
