Product Specification

OS-950 Miniature Plastic Optical Liquid Level Sensor

The OS950 miniature optical level sensor is distinguished by its polysulfone polymer housing and lack of moving parts. This plastic level switch is ideal for point level monitoring in medical diagnostic equipment, dialysis systems, sterilizers and washers, and other OEM industrial and medical applications.

Built-in optical electronics provide a switched output level sensor that can sense the presence or absence of fluids in temperatures up to 125°C and pressures up to 250 PSIG.

OS-950A "ON" when Wet (wet sink output)
OS-950B "ON" when Dry (dry sink output)
