    Photocells | Photoelectric sensors

    The photoelectric sensors in our range come from Telco SensorsTelco Sensors is a Danish developer and manufacturer of a wide range of products such as; photoelectric amplifiers, diffuse proximity sensors, retro-reflective photoelectric sensors, thru-beam sensors, light grids and photoelectric fork and frame sensors. Telco Sensors is known for its high quality, which is very important to Sensor Partners . The quality is proven by its insensitivity to light pollution and accumulations of moisture and dirt in the most challenging environments that other optical sensors suffer from. In addition to this, the photoelectric sensors are waterproof and can take a hit, literally! Where other sensors fail due to environmental conditions such as shock, dirt and water, the photoelectric sensors from Telco Sensors keep going.

    Sensor Partners also offers a wide range of photoelectric sensors from Micro Detectors. Micro Detectors is an Italian developer and manufacturer of a wide range of photoelectric sensors, ultrasonic sensors, proximity switches and more. The technology, quality and performance of these sensors, resulting from a long tradition in this sector, is emphasized by a service level based on speed and flexibility. The M.D. sensors are known for how robust and durable they are, even in poor conditions.

    As a knowledge partner Sensor Partners, advises and supports its customers in the use of photoelectric sensors, and we, together with the customer, realize the most challenging applications every year. We are also at your service for special designs and custom-made adjustments, so get in Contact through e-mail or phone.

    • Telco Sensors transmitter and receiver photoelectric sensors

      Thru-beam

      Photoelectric sensors with a single transmitter and single receiver are placed in opposite to each other. The transmitter sends an infrared beam to the receiver. When an object interrupts the light beam, the output is activated. A transmitter/receiver photoelectric sensor is a very reliable way of detecting and the high excess gain of our sensors are suited for extremely polluted environments. Our thru beam sensors can reach up to 70 meters!
    • Diffuse proximity sensors

      Photoelectric diffuse proximity sensors can have various names in the market, such as diffuse photoelectric sensors, diffuse proximity switch or reflex sensor. The principle of the diffuse proximity sensor relies on object reflection. Thus, the photocell uses the reflected light from the object in front of the sensor.Our range of probe photocells is carefully composed of the most capable and versatile sensors for the best fit for the most challenging applications. For example, such as performing detections at a supply conveyor in a sorting machine for waste disposal.. The sensors have a high tolerance to dirt and moisture thanks to the high protection classes; from IP65 to IP69K!Aligning the photocells in the application and following the detections with the naked eye are also made possible by the models equipped with a visible red light instead of (invisible) infrared light.With these photocells, the transmitter and receiver are always in the same housing, so the emitted light falls back into the receiver as a reflection.
    • Photoelectric sensors with background suppression

      Photoelectric sensors with a background suppression function as a photoelectric sensor with diffuse proximity or reflex barriers, with an additional function. These sensors only detect objects within a defined zone. The sensor detects everything that passes between the sensor and the taught background.
    • Retro-reflective photoelectric sensors

      In retro-reflective photocells, or reflector photocells, the transmitter and receiver are in one housing just like in probe photocells. However, the photocell now always faces a reflector, which is placed opposite the photocell.The output of the photocell is activated as soon as an object passes between the photocell and the reflector. Unlike normal reflective sensors, polarized retro-reflective photocells (reflector photocells) use special polarization filters so that the receiver only accepts light that is reflected from the reflector and not from another reflective object, such as metallic car paint. Thus, one can also flawlessly detect translucent and reflective objects.Thus, a major advantage of these polarized reflector photoelectric sensors is that they are not prone to false detections.

    • Amplifier photoelectric sensors from Telco Sensors

      Amplified photoelectric sensors

      The LT and LR series from Telco Sensors are a range of amplified photoelectric sensors. These photoelectric sensors are connected to PA, PMA or PAB amplifiers. Photoelectric sensors with a separate amplifier are available in a variety of sizes with fixed cable or a connector with a maximum range of up to 70 meters. The use of separate amplifiers allows the user to make use of a compact sensor but still have excess power to use in applications with a lot of dirt buildup. In addition, the amplifier provides extra flexibility with the inifinite sensitivity adjustability and on/off delay. The amplifiers are available in 24 Vac/Vdc or 230 Vac.
    • Frame sensors

      Like the fork sensors, frame sensors are optical sensors, where the transmitter and receiver are placed facing each other in a U-shaped aluminum housing or a closed crossbar housing.
    • Fork sensors

      Fork sensors are photoelectric thru-beam sensors in a aluminium fork housing. These type of sensors are, because of the high switching frequency (up to 10 kHz), ideal for high-speed detection and counting applications where accuracy and reliability are of great importance. For applications with even higher counting and detecting speeds there are photoelectric laser sensors with switching frequencies of up to 300 kHz!
