optoNCDT 1420

A class of its own: compact, precise & high speed

New: Smart Laser Displacement, Distance and Position Sensor

Smart sensors for fast and precise measurements

The new optoNCDT 1420 laser triangulation sensor offers a unique combination of speed, compact size and performance capabilities, opening the door to a vast array of new application possibilities for displacement, distance and position measurement tasks.

The sensor has the same compact dimensions as the optoNCDT 1320 (46mm x 30mm x 20mm) but furthermore comes with additional performance features.  Although Micro-Epsilon classes the optoNCDT 1420 as a mid-performance laser displacement sensor in our product portfolio, the actual performance and smart features exceed many high-performance sensors currently on the market.

Not only is it extremely compact in size, the laser triangulation sensor also achieves a high measurement accuracy at measuring rates of up to 8kHz. The Active Surface Compensation (ASC) ensures stable measurement results regardless of changing surface colours or brightness. The sensor also benefits from a competitive pricing structure, making it suitable for both single piece and higher volume OEM applications.

The Active Surface Compensation (ASC) provides stable measurements regardless of target colour or brightness. Precision optics normally found in more expensive sensor series create sharp and small diameter spot geometries, enabling very small objects to be reliably measured.

Highest precision in a compact size

The compact size combined with low mass opens up new fields of application. For example, mounted on robot arms or in pick-and-place machines.

In addition, selectable voltage, current and digital RS422 outputs enable integration of the sensor into almost any measurement process, test facility or machine control system.

The optoNCDT 1420 sensor is available in measuring ranges of 10mm, 25mm or 50mm.

Smart functionality

The optoNCDT 1420 models enable quick sensor commissioning with just a few clicks using the multifunction 'sensor' button.

Additionally a simple and intuitive web interface can be used to setup and download the sensor parameters. The interface even has pre-defined sensor configurations for the most common surface types, for example 'transparent', 'translucent' and 'opaque', enabling faster setup and optimum sensor configuration.

Further SMART functions include video signal display, selection of individual signal peaks and ROI (region of interest) function which allows interference signals not in the measurement zone to be filtered out. 

For users of multiple sensors with the same configuration, a ‘save’ and ‘download to sensor’ feature prevents individual sensor setup and saves time.

Also available with laser class 1

The optoNCDT 1420 CL1 series is designed for measurement tasks with increased safety requirements. These sensors are classified according to laser class 1. With this laser class, the radiated power is at a maximum of 390 µW. Therefore, costly protective measures that correlate with laser class 2 sensors are no longer necessary. The optoNCDT 1420 CL1 models are used for measurement tasks where people work close to the sensor, and for distance measurements on sensitive surfaces.
