Description
Baumer PL20H is a hygienic capacitive level switch designed for point-level detection in food, beverage, dairy, and pharma applications. Using smart capacitive sensing with IO-Link, it provides reliable switching even in foams, sticky fluids, viscous media, and CIP/SIP conditions. Its 316L polished housing, high-temperature resistance, and flexible configuration make it ideal for hygienic tanks and process lines.
