optoNCDT 1420

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

Smart laser triangulation displacement sensor

Smart sensors for fast and precise measurements

The optoNCDT1420 offers a unique combination of speed, size, performance and application versatility for displacement, distance and position measurements. The compact triangulation sensor achieves a high measurement accuracy and measuring rates of up to 8kHz. The selectable connector type, i.e. cable or pigtail, together with compact size reduce the sensor installation effort to a minimum. Just like all triangulation sensors from Micro-Epsilon, the optoNCDT 1420 provides an intelligent surface regulation. The Active Surface Compensation (ASC) ensures stable measurement results regardless of changing surface colours or brightness. The high-performance optical system generates a small light spot which enables to even detect smallest components reliably.

Highest precision in a minimum of space

Compact size combined with low weight opens up new fields of application. As well as analog voltage and current outputs and a digital RS422 interface enable to integrate the sensor into plant or machine control systems. Due to the selectable setting and evaluation possibilities, the optoNCDT 1420 meets the requirements for use in high volume and OEM applications.

Unique ease of use

All optoNCDT 1420 models are operated using an intuitive web interface. Presets and a quality slider for the selection of the measurement task enable the sensor parameter set up. Up to eight user-specific sensors settings can be stored and exported in the setup management. Set ups can be quickly and easily saved, loaded and transferred to further sensors. The video signal display, the signal peak selection and a freely adjustable signal averaging enable to additionally optimize the measurement tasks. The ROI function (region of interest) allows e.g. for interfering signals in the background to be filtered out. The multifunction button enables quick sensor commissioning.

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.
