The OD2-N85W20A2 is a 2D laser displacement sensor from the OD Value series, delivering an NPN output for profile measurement. It operates from a 12 ~ 24VDC supply and is rated IP67 — dust-tight and protected against water immersion, so it holds up in washdown or outdoor environments without an extra enclosure. The sensor's standoff range is 65.0 mm to 105.0 mm, with a measurement span of ±20 mm around an 85 mm nominal center. That means it reads height, gap, or position profiles across a 40 mm window, which suits part-present verification, weld-seam tracking, or adhesive-bead inspection on a moving line. It is chassis-mounted and terminated with cable leads — no connector to swap, so the wiring is permanent once landed. Operating temperature is -10°C to 40°C, which covers most indoor production floors but not a freezer or foundry without thermal management.
The 65.0 mm to 105.0 mm installation distance is the range over which the sensor achieves its specified ±20 mm measurement window. Mounting closer than 65 mm or farther than 105 mm degrades accuracy or loses the target entirely — the standoff bracket must be set within that band. The chassis-mount form factor bolts directly to a machine frame or a custom bracket; no DIN rail is involved.
