The QFRS-BP-1F from Micro Detectors is a photoelectric sensor with background suppression with a range of up to 6 m in a cubic stainless steel housing with ECOLAB certification. The QFRS/BP-1F can detect products or objects superfast because of the high switching frequency of 1 kHz, without the need for a reflector. The ECOLAB housing and the IP68 and IP69K protection class make this sensor suited for applications in the food industry or applications in which the sensor is exposed to water and cleaning agents. The photoelectric sensor has a 4-pin M8 connector and a digital PNP NO+NC output. The range of the sensor is configurable through a potentiometer.


QF series from Micro Detectors

The QF series from Micro Detectors is a series of photoelectric sensors in cubic stainless steel mini-housing. The sensor has a IP67, IP68 and IP69K protection degree and so specially suited for challenging envurinmonts, such as in the food and beverage industry. The photoelectric sensors use a LED with visible red or infrared light.

All models in the QF series photoelectric sensors have a reverse polarity protection and they are short-circuit proof. All models also include a potentiometer with which you can install the sensitivity of the photoelectric sensor. The sensors also have a high switching frequency, so they can be deployed in fast detection applications.

The models of The QF series photoelectric sensors are available in various versions, namely: as a diffuse proximity sensor, polarized retro-reflective sensor, sender/receiver sensors or as sensor with background suppression. The QF series has besides the difference in detection mode also models available with diffferences in the measuring range and the connection.
