Low-cost fork sensor is `world’s smallest`

28 October, 2009

Leuze electronic has developed what it believes is the world’s smallest industrial fork sensor for detecting labels. The low cost of the GS 61 means that that it can be used where previously microswitches or other techniques might have been preferred.

The sensors have a flat bottom, allowing them to be mounted close to the dispensing edge for good response times and repeatability. Sensitivity is adjusted using a teach-in pushbutton or a potentiometer, depending on the model. Neither technique needs tools.

Leuze, which claims to be the world leader in the fork sensor market, has also produced a variant called the GS 63, which offers a high switching frequency and short response times. An “auto level control” function allows the sensor to correct its switching threshold automatically during operation to compensate for varying properties in the labels and their backing.

The sensors offer a choice between fixed cables or M8 connectors with top or side outlets, making it easy to install them in small spaces.
