The miniaturised photoelectric sensors from the FTPS series have the compact construction particularly suitable for installation in tight spaces. There are four detection systems provided in the NPN and PNP versions from 12-24Vdc: direct reflection onto the material with and without background suppression, polarised reflection with reflector and barrier projector+receiver. The sensitivity is regulated by a potentiometer as well as a green stability LED which, when fully on, indicates that the adjustment has been successful. A special selector can be used to operate the light/dark impulse switch, choosing the function needed when using it. The level of protection is IP67 and the whole series is supplied, for the electrical connection, with a push-pull M8x1 connector, thus enabling the photocell to be positioned in the installation thanks to the mobility of the output cable and benefiting at the same time from the connector being fitted a few centimetres away from the photocell itself.
