Balluff’s new BKT 67M contrast sensor range provides a low-cost solution for registration mark and contrast applications.

There are three models to choose from (basic, advanced and premium) and the user can select the most appropriate sensor for his or her application.

An aluminium housing, programmable time delay, output settings and on-the-fly target colour adjustment are a few of the features designed to solve challenging targets.

This BKT 67M has a reliable switching response to ensure maximum contrast difference between marking and background; a built-in microcontroller automatically selects either red-, green- or blue-light emission during the teach-in process.

The sensors then function as light-on or dark-on, depending on the existing contrast conditions.

If the user needs to perform fine adjustments of the switching threshold, the advanced and premium versions are recommended.

The basic version is said to be the most economical solution and includes the most commonly used functions.

The basic model is a simple but effective device for detecting all standard contrast marks with an excellent price-performance ratio, according to Balluff.

The advanced model is ideal for controlling fast packaging processes with a 20kHz switching frequency.

In addition, a manual adjustment compensates for contrast tolerances.

To monitor the sensor settings, there are four light-emitting diodes (LEDs) and a bar-graph display.

For high-speed applications, the most appropriate solution is the premium model, which has a 30kHz switching frequency.

It can be calibrated on the fly and has a four-digit display for setting up complex contrast relationships.
