SD Optical Level switching
NPN, PNP open collector output to energize relay or PLC SUPPLIERS
Outer material of PC, Polysulfone,
SUS304/316 for acidity and alkaline; applicable in grease, waste water, liquid solution, liquor, alcohol....etc
Over-current and reverse polarity protection
LED status indication
Application: liquid leakage detection motor/pump protection
The ir sensor can precisely detects the liquid level, and the internal professional filter circuit can prevents error switching contact caused by the interference of ambient light and sunlight. The NPN or PNP open collelctor can drives laod up to 100mA max.
Features: It's small size, easy installation and suitable for application in liquid with mixed materials or slurries. The encloosure is made in PC that can resist oil and acid/corrosion. Several switches can be used at the smae time won't be interrrupted by each other. It can be hooked up relay and PCL for application.
