M30 Capacitive Proximity Sensor featuring trademarked 4th Generation TRIPLESHIELD protection from static electricity, transient bursts and the effects of line induced noise (typically attributed to variable frequency drives). Adjustable 4-30mm sensing distance; 10 to 40VDC supply voltage, with both a normally open and closed 200mA PNP transistor output. Dual LED indication assists in installation and troubleshooting. These sensors are typically used in detecting water through a sight glass, regrind in a plastic hopper and grain in a silo. There sensing face is rated to 248 degrees Fahrenheit for high temperature applications. There is also an optional ‘Dust’ or ‘Temperature’ Alarm output.
