The SICK OD2-N30W04A2 is a 2D laser displacement sensor from the OD Value series, delivering a 30mm measurement range with ±4mm linearity. It outputs an NPN signal, so it pulls the line low when the target is within the detection window — standard for PLC sinking inputs or older controller cards that expect a current-sinking signal. The 12~24VDC supply range covers common industrial power rails without needing a separate regulator. Installation distance is 26.0mm to 34.0mm from the target, so the bracket or fixture needs to hold that standoff within about ±4mm. The cable leads termination means no connector to swap — you wire directly into the control cabinet or junction box, which saves a failure point in high-vibration environments.
Operating temperature and environment
Rated for -10°C to 40°C ambient, so it handles unheated warehouses and conditioned production floors but not freezer tunnels or oven-adjacent stations. If the line runs hot (near ovens, dryers, or foundry areas), you'll need a sensor with a wider thermal range or a cooling shield.
