Sensing range and axis layout
This Autonics BW40-08 area sensor uses a through-beam method with eight optical axes spaced at a 40 mm pitch. It detects objects from 0.1 m up to 7 m using an 850 nm infrared LED. The unit operates on a 12-24 VDC supply and provides an NPN open-collector output in Light ON mode.
Suitable applications and limits
The sensor suits production lines, packaging machines and safety zones that need multi-point detection across a defined curtain. Installations requiring a different axis count, a longer or shorter range, or a PNP output type should consider other models.
Deciding specification
The eight-axis array at 40 mm pitch sets the detection resolution and coverage height, making it the single figure that confirms whether this sensor matches the application.

Questions about this item
What supply voltage must my panel provide for the BW40-08 sensor to operate?
The sensor requires 12-24VDC with a maximum 10% ripple on the power line.
Can the NPN open-collector output drive a legacy PLC input that expects a sinking signal?
Yes, the control output is an NPN open collector configured for Light ON operation, compatible with sinking inputs.
How do I verify the 8-axis detection zone is aligned correctly after mounting?
With the beam unbroken, the output stays active in Light ON mode; interrupting any of the 8 axes at 40mm pitch switches the output off.
