High-performance, compact triangulation sensors

16 January 2016

Micro-Epsilon UK has introduced a range of laser triangulation sensors with integrated controller that offers a combination of compact size, good performance (up to 4kHz measuring rate) and ease of installation.

Two new sensor ranges are available: the optoNCDT 1320 and the optoNCDT 1420 laser displacement sensors. The optoNCDT 1320 is the entry-level version for high precision measurement of displacement, distance and position. The controller is integrated in the sensor housing, which simplifies installation and set up.

The optoNCDT 1320 is compact (46mm x 30mm x 20mm), lightweight (30g) and so can be mounted in tight spaces on machines or other difficult-to-access locations. It offers high accuracy and adjustable measuring rates up to 2kHz, and has a novel ‘Auto Target Compensation’ (ATC) feature, ensuring stable distance signal control regardless of target colour or brightness.

With identical dimensions to the optoNCDT 1320, the optoNCDT 1420 is designed for high precision, high speed, dynamic displacement, distance and position measurement applications. The measuring rate is adjustable up to 4kHz and the sensors offer a good price-performance ratio, particularly for high volume OEM applications.

A range of different output signals enable easy integration of the sensor into plant or machine control systems. As well as analogue voltage and current outputs, a digital RS422 interface provides distance information from the sensor. All optoNCDT 1420 sensors operate using a web interface for fast sensor set up and configuration. Up to eight user-specific sensor settings can be stored and easily exported to other sensors.

Additional features include video signal display, signal peak selection and freely adjustable signal averaging, which enables optimisation of the measurement task. A region of interest (ROI) function allows background signal noise to be filtered out.

The optoNCDT 1320 and 1420 series are available in measuring ranges of 10mm, 25mm or 50mm.
