The SICK OD1-B035C15I14 is a 2D laser displacement sensor from the OD Mini series, delivering a 4-20 mA analog output proportional to the displacement of a target within a 20.0 mm to 50.0 mm installation distance. That 4-20 mA loop is the signal you'll land on a PLC analog input card — clean, industry-standard, and easy to troubleshoot with a DMM in series. It's rated for 12 ~ 24 VDC supply, which covers the common panel supply rails.
Signal integrity and deployment context
Termination is via an M8 connector (4-pin), which means the cable is field-replaceable — a practical advantage when a cable gets pinched in a robot cell or conveyor track. The operating temperature range of -10°C to 40°C is typical for indoor industrial environments; if the sensor is near an oven or in a foundry, you'll need to shield it from radiant heat or move it outside the hot zone. Chassis-mount form factor, so it bolts to a bracket or machine frame. The 4-20 mA output is a current loop, which is inherently more noise-immune than a voltage output over long cable runs — important if your cable tray runs parallel to VFD motor leads. Check the shield first if the signal drifts.
