OLSx Optical Liquid Level Sensors

Cynergy3 / Sensata OLSx Series Optical Liquid Level Sensors are designed for single-point liquid level detection. The cost-effective sensors feature an infrared emitter and detector aligned within a cone for optimum optical coupling. The units offer a transistor output that allows users to configure the output to meet particular applications. Cynergy3 / Sensata OLSx Series Optical Liquid Level Sensors are available in M10x1, M12x1, and 1/4"NPT external mount threads.
