Thru-beam

A transmitter/receiver photoelectric sensor is a very reliable way of detecting and the high excess gain makes them particularly suitable for extremely polluted environments. Think of applications in waste and environmental technology. Our transmitter/receiver photoelectric sensors can be up to 70 meters apart! Read more about the operation of photoelectric sensors here. Below you can get an impression of the wide range that we offer as Sensor Partners.

The SM3000 series

The Telco Sensors SM3000 photoelectric sensors are a series of transmitter/receiver photoelectric sensors with a range of 6 or 15 meters and available in various housings, including Ø10, Ø12.7 snap, M12x1 and miniature cube housings in the materials plastic or brass. In addition, there is the possibility to choose between versions with a fixed cable or a connector. The sensitivity of the sensors is adjustable through control input and are equipped with power and output indication. In addition to the standard versions, we also supply a TÜV certified version (AOPD) for industrial doors and fencing EN12978. The series has been developed for compactness without compromising on robustness of the housing. This makes the photoelectric sensors disreetly installable in different industrial applications, where for example dirt buildup or exposure to water occurs. The SM3000 series is widely used in logistics processes, conveyor belts and packaging machines, but also in access technology on gates, fencing and lifts.

The SM6000 series

Telco Sensors' SM6000 series differs in speed compared to the SM3000 series. The version with a range of 2 meters has a switching frequency of 1000 Hz and a response time of 0.5 ms. The version with a range of 6 meters has a switching frequency of 100 Hz. The transmitters (SMT) from this series can be combined with both the 2 meter and the 6 meter variant of the receiver (SMR).

The SM7000 series

The 7000 series photoelectric sensors consists of multiple versions such as a transmitter and receiver but also diffuse proximity. This serie characterises itself with a 4-wire design which allows ambivalent switching between NPN- and PNP-switching outputs. This means that the switching output can be configured as NO (Normally Open) as well as NC (Normally Closed).

The SM9000 series

The Telco Sensors SM8000 is a series of transmitter/receiver photoelectric sensors with an adjustable range of up to 20 meters. The plastic or stainless steel M18 housing is equipped with a potentiometer for the sensitivity setting as well as setting a PNP NO or NC output. In addition, you can choose between a 5-meter fixed cable or a 4-pin M12 connector.

The SM9000 series

The Telco Sensors SM9000 series is a unique series of transmitter/receiver photoelectric sensors that distinguish themselves with their extreme power. This makes the photoelectric sensor suited for applications in which they are exposed to a lot of dirt, water and light or where large distances are bridged, but also for applications with a lot of dust, fog, smoke or mist. The photoelectric sensors have an M18 threaded housing and IP69K sealing degree. Cleaning the sensors under high pressure is therefore no problem. The SM9000 series is equipped with a PNP NO/NC output or a solid-state relay. In addition, the series is also available with ATEX certification for Zone 2 and 22.

The SP2000 series

The SP2000 photoelectric sensors from Telco Sensors in transmitter/receiver configuration have a range of 45 meters and use the well-known 50 x 50 mm housing. The photoelectric transmitter and receiver combination has a relay output and 12-240 Vac/dc supply voltage as standard. The sensitivity and on/off delay are adjustable via potentiometers.

The FA series

The FA series from Micro Detectors are photoelectric sensor in a M18 housing. The sensors from this series exist of models with a right-angled or axial sensor head, have a aluminium or metal housing and have an IP67 protection degree.

The QM series

The QM series of Micro Detectors is a serie photoelectic sensor in cubical plastic mini housing. The QM series also has a high switching frequency, which makes the sensors suited for accurate detection and positioning applications, also in fast applications. The models from the QM series photoelectric sensors are available as a diffuse proximity sensor, a polarized retro-reflective sensor, a retro-reflective sensor for detection of transparant materials, as a transmitter/receiver or as a sensor with background suppression.

The QF series

The QF series from Micro Detectors is a series of photoelectric sensors in cubic stainless steel mini-housing. The sensor has an IP67, IP68 and IP69K protection degree and is therefore specially suited for challenging envurinmonts, such as in the food and beverage industry. The sensors are availabe as a diffuse proximity sensor, a polarized retro-reflective sensor, as a transmitter/receiver or as a sensor with background suppression.

The QE series

The QE series from Micro Detectors is a series of photoelectric sensors in a aluminium mini-housing available in the following configurations: diffuse proximity, background suppression and polarized photoelectric transmitter and receiver sensors. The sensors are equipped with a switching frequency of 1 kHz for use in high-speed applications.

The FF series

The FF series from Micro Detectors are photoelectric sensors in a stainless steel M18 housing. With the ECOLAB- certification and the IP69K housing this sensor is suited to use in applications with foods and liquids. The FF series is available in different configurations: As a diffuse proximity sensor, a polarized retro-reflective sensor or as a transmitter/receiver. It is possible to order ATEX-compliant models if desired.

The MS series

The MS series of Micro Detectors consists of a wide range of photoelectric sensors in a stainless steel M18 housing. The sensors are available with a axial or right-angled sensor head. The MS serie has different configurations: diffuse proximity, retro-reflective (also polarized), transmitter and receiver photoelectric sensors (thru-beam) and photoelectric sensors with background suppression.
