Fork sensors and optical windowsVorksensoren voor detectie van kleine objecten met hoge schakelfrequentie - SensoPart

Due to their special design, fork sensors and optical windows have characteristic properties. They are particularly suitable for detecting small objects with a high switching frequency. In addition, the sensors are very easy to mount without time-consuming alignment.

Fork sensors

SensoPart fork sensors work according to the transmitter-receiver principle. The transmitter is located in one arm and emits the light to the directly opposite receiver in the other arm. The transmitter and receiver are then immediately perfectly aligned. This means you have less cabling and you save installation time. Fork sensors have multiple mounting options and are therefore easy to integrate into a machine design.

Small objects with a high switching frequence

Due to the perfect alignment, very small objects with a diameter from 0.2 mm can be detected accurately and with a high switching frequency. Fork sensors are available in a plastic or metal housing in various fork widths (5 ... 220 mm) with red light or invisible infrared light. Typical applications for the fork sensors are the accurate detection of small parts on vibratory fillers or the precise positioning of objects. Special versions are available for detecting labels.

Optical window

Raamsensor voor uitwerpcontrole van kleine onderdelen - SensoPart

Strictly speaking, a window sensor is a transceiver light curtain. Several transmitter-receiver sensors are integrated and aligned on two opposite sides. The light modulation and the special geometric arrangement ensure that the different beams do not influence each other.

The number of beams in the housing is a measure of the resolution of the window sensor and thus determines the minimum object size of the object to be detected. A window sensor is easy to align, has only one connector and is therefore easy to commission. A typical application for window sensors is the rejection control of small parts, for example in an injection molding machine or punching machine.

Decisive for reliable detection of small objects is the resolution of the beams and the response time. Objects with a diameter from Ø 0.8 mm can be detected. With a dynamic signal evaluation it is even possible to reliably detect objects through transparent hoses.
