Miniature sensors

Miniature sensors have a small housing and can be used in the smallest spaces and moving machine parts. Miniature sensors are available as LED and laser versions and are one of the most extensive series of sensors on the market. The precise background suppression, adjustable via teach-in, makes the miniature sensors unique. The light spot of the miniature sensors remains so concentrated that small parts in the millimeter area are still detectable, even over long distances of 60 mm.

Blue light miniature sensor

The miniature sensor with blue light has been specially developed for detecting solar wafers and highly absorbent objects, using the scanning principle.

The miniature sensors have a degree of protection from IP64 to IP67 and have different connections: M5 connector 4-pin and M8 connector 3, or 4-pin.

Miniature sensor with laser light

The only miniature sensor with laser light

That small sensors can deliver great performance is proved by the photo cell series F 10-series by SensoPart. The F 10-series is the first and only miniature sensor based on laser light. Also, the adjustable background suppression makes the sensor, in combination with the small construction type, unique. Thanks to the unique specifications and the easy to use details these compact sensors can be used in almost any application.

User-friendly teach-in button

The F 10-series sensors are the world's smallest laser sensors. The sensors are adjustable via the user-friendly electronic teach-in button or control wire. The sensors are designed as LED and as laser version. Especially for the scanning of solar wafers and highly light absorbing objects, SensoPart has the FT 10-series blue light version.

Reliable detection

The light spot of the F 10 laser sensors remains so concentrated that even small parts in the millimeter range are still reliably detected even at long distances, for example a wire with a diameter of 0.5 mm at a distance of 60 mm. The F 10-RLH is the only sensor of its kind with the possibility to adjust the scanning distance.

Miniature sensors for distance measurement

With a measuring range between 10 and 70 mm with a blind zone of only 10 mm, the FT 10-RLA guarantees reliable detection of small parts.

Analog switching output

The smallest distance sensor is suitable for distance measurement during assembly of semiconductor devices, thanks to the analog switching output. With a weight of only 10 grams, the sensor is also ideal for robotics applications. Read more about analogue sensors for distance measurement.

Simple assembly

The dovetail mounting system, in particular, simplifies fine-tuning, especially in difficult installation locations and the various connection variants make rapid commissioning and replacement possible.

The mounting holes of the miniature sensor are reinforced with metal eyelets.

Photo electrical proximity sensor - Blue light

The FT 10-BF Blue light photoelectric proximity sensor with background suppression has a fixed scan distance or focus in contrast to the F 10-RLH. The FT 10-BF remains reliable when scanning highly light-absorbing and transparent objects, such as light wafers.

Incorrect alignment not possible

With the design of the sensor, incorrect alignment is not possible. Thanks to the dovetail attachment, the sensor is easy to dishonor and adjust.

Miniature sensor for detecting transparant objects

Transparent objects pose special challenges for sensors because their low absorption rates require very high switching sensitivity and accuracy.

The special retroreflective photoelectric sensors (FR 25-RGO), as well as ultrasonic sensors (UT 20, UT 20 Soundpipe, UMT 30 and cylindrical housings), are reliable for detection of transparent objects. Read more about detection of transparent objects.

Miniature sensor for front detection, pick & place and quality check - SensoPart

Miniature sensor for front detection, pick & place and quality check

In order to be able to pick up a workpiece or component from a belt with a targeted robot gripper one has to know the exact position in advance. The FT 10-series miniature sensors and FT 25-series contrast sensors are ideally suited for such tasks.

Vision camera for detection, pick & place and quality checks

If, in a pick & place application, the X-/Y-position and orientation are also required, or if complex assemblies must be inspected for correct and complete assembly, we recommend our vision sensors in the VISOR® series, which can detect several features in a single pass. Read more about vision sensors and cameras.
