DT50-N1123

What type of sensor is this device?

It is an industrial laser distance sensor that uses time-of-flight technology to measure the distance between the sensor and natural objects.

What is the measuring range?

The measuring range depends on the target reflectivity. It extends from 200 mm to 10,000 mm at 90% reflectivity, 200 mm to 5,000 mm at 18% reflectivity, and 200 mm to 2,500 mm at 6% reflectivity.

What measurement accuracy does the sensor provide?

The DT50-N1123 provides a measurement accuracy of ±10 mm under the specified conditions, with a resolution of 1,000 µm and repeatability of at least 2.5 mm.

What outputs are provided?

The sensor has one NPN digital output and one 4–20 mA analogue current output. The analogue output has 16-bit resolution and supports a load of up to 300 Ω.

What supply voltage is required?

The device operates from a 10–30 V DC supply and consumes no more than 2.1 W without an output load.

How quickly does the sensor respond?

Its response time is configurable between 20 ms and 30 ms, depending on the selected fast or slow moving-average setting. The output time is at least 4 ms.

What connector does the device use?

It uses a 5-pin, A-coded M12 male connector. Compatible straight or angled female sensor cables can be selected according to the installation requirements.

What is the connector pin assignment?

Pin 1 is L+ for the supply, pin 2 is the analogue output QA, pin 3 is M or supply common, pin 4 is the digital output Q, and pin 5 is the multifunction input MF.

What can the multifunction input be used for?

The multifunction input can be configured for switching off the laser, performing an external teach operation, or remaining deactivated.

Can the switching point and output behaviour be configured?

Yes. The digital and analogue outputs support teach-in, scaling and inversion. The digital output also offers adjustable hysteresis from 10 mm to 1,000 mm.

What environmental protection does the housing provide?

The sensor has an IP65 enclosure rating. Its housing is made from zinc die-cast metal, while the optical window is manufactured from PMMA plastic.

What operating temperatures are supported?

The standard operating range is −30°C to +65°C. With two suitable cooling plates it can operate up to +80°C, or up to +140°C when the cooling plates are combined with the appropriate heat-protection filter.

What are the device dimensions and weight?

The unit measures 36.1 mm wide, 62.7 mm high and 57.7 mm deep. It weighs approximately 200 g.

What type of laser does the sensor use?

It uses a visible red, Class 1 laser with a wavelength of 658 nm. The typical light spot size is 15 mm × 15 mm at a distance of 10 m.

Does the sensor include a local display?

Yes. It has an LC display and two LED indicators for local status information and parameter adjustment. The display can also be switched off and the user interface can be locked.

What applications is this sensor suited to?

Typical uses include object positioning, distance monitoring, level measurement, material-handling equipment, storage systems and industrial process control where non-contact measurement of natural targets is required.
