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.

  • Sender receiver

    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

    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 is based on object reflection. The photoelectric sensor thus uses the reflected light of the object that is in front of the sensor. In the case of diffuse proximity sensor, the transmitter and receiver are always in the same housing, so that the transmitted light is reflected in the receiver as a reflection. Because object reflection is used, the maximum detection distance is always affected by the degree of reflectivity of the object. Keep this in mind! Our diffuse proximity sensors are known for their robust housing and low sensitivity to pollution. The sensors are NO/NC adjustable. The sensitivity is adjustable via a potentiometer.
  • Photoelectric sensors with background suppression

    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

    Retro-reflective photoelectric sensors

    With retro-reflective photoelectric sensors, or reflector sensors, the transmitter and receiver are located in one housing, just like with the diffuse proximity sensors. However, the retro-reflective sensor now always looks at a reflector, which is placed opposite of the sensor. The output of the sensor becomes active as soon as an object gets between the transmitter and receiver.
  • Amplified photoelectric sensors

    Amplified photoelectric sensors

    The LT and LR series of Telco sensors is a series of amplifier photocells. These amplifier photocells are connected to PA, PMA or PAB amplifiers. Photocells with separate amplifier are available in various designs with fixed cable or connector with a maximum range of 70 meters.
  • Frame sensors

    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

    Fork sensors are photoelectric thru-beam sensors in a aluminium fork housing. These type of sensors are, because of the 5 kHz switching frequency, 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 a switching range of up to 300 kHz!
