What the sensor does

The Banner LT3PU is a time-of-flight laser distance sensor that measures from 300 mm to 5000 mm using a visible red Class 2 laser at 658 nm. It runs on 12-24 V dc and provides both a 0-10 V analog output and a single PNP discrete output with short-circuit protection. The rectangular ABS housing carries an 8-pin, 2 m cable and is rated IP67 and NEMA 6 for harsh environments.

Who it suits and who it does not

Engineers needing non-contact distance data on conveyors, packaging lines or robotic cells will find the 1000 ms power-up delay and push-button or remote teach adjustments practical. Buyers who require a quicker response than the slow-speed repeatability of 1 to 1.25 mm or who need a quick-disconnect fitting instead of a fixed cable should look at other models.

Behaviour under sustained load

The analog output drives a minimum 2.5 kΩ load while the PNP output switches up to 100 mA with saturation below 1.2 V at 10 mA and below 1.6 V at 100 mA. Temperature drift is specified at 2 mm per °C, so long runs in varying ambient conditions will see a predictable shift rather than sudden deviation. Output protection guards against short circuits during continuous operation.

Questions about this item

What power supply must I already have to run this 12-24 V dc sensor?

You need a stable 12 to 24 V dc source capable of delivering the sensor's operating current; the unit draws power through its 2 m cable and requires 1000 ms at power-up before measurements are valid.

Can the PNP discrete output on this LT3PU drive a legacy 24 V dc relay coil directly?

Yes, the single PNP output switches up to 100 mA with saturation below 1.2 V at 10 mA and below 1.6 V at 100 mA, and it is protected against short circuits.

How do I verify the analog output is tracking distance correctly after installation?

Measure the 0 to 10 V dc signal across a load of at least 2.5 kΩ; at 300 mm the voltage should be near 0 V and at 5000 mm near 10 V, with repeatability of 1 to 1.25 mm at slow response speed.
