Long-range diffuse sensor

The Banner QS30LD is a Class 1 laser diffuse sensor that detects objects up to 400 mm using a visible red beam. It operates on a 10-30 V dc supply and connects via a 2 m cable with five conductors. The rectangular housing features an M30 mount and carries NEMA 6 and IP67 ratings for harsh environments.

Industrial automation and process control

This sensor suits engineers who need a compact, bipolar output device with NPN and PNP signals for programmable logic controllers. Its 0.5 ms response time and 70 µs repeatability support fast counting or positioning tasks. Buyers who require a through-beam pair, a longer sensing range, or a quick-disconnect fitting should look at other models.

400 mm sensing distance

The maximum range of 400 mm is the critical figure that determines whether this part fits the application. A 650 nm laser spot provides a small, visible aiming point for precise alignment. The teach button allows quick setup for light or dark operate modes without external tools.

Questions about this item

Will the 10-30 V dc input range let me run this sensor on the same supply rail as my existing 10-30 V dc devices?

Yes, the sensor operates from 10-30 V dc, so it can share a supply rail with other equipment rated for that same voltage window.

How can I verify the QS30LD is detecting targets correctly after mounting it?

The unit has indicator LEDs that show output status; a taught target at up to 400 mm will toggle the bipolar NPN and PNP outputs with a 0.5 ms response time.

What comes in the box with the QS30LD and what must I source separately?

The sensor ships with a 2 m (6.5 ft) 5-wire cable permanently attached; mounting brackets, a separate power supply, and any teach-remote accessory are not included.
