New long range photocells For very long range tasks there is now a new option in photoelectric sensors following the launch of ifm electronic’s new cabled O4 range. Experience has shown that photoelectric sensors do not need to be changed often, especially the longer range versions mounted out of harm’s way, so a cabled option can be attractive. These long-range photocells with an integral 2m PUR cable are ideal for use in wood, paper and automotive industries, transport and conveying, steel processing. The sensing ranges on offer are more than enough for long distances or to power through dusty of steamy atmospheres. A range of 80m from the O4E/O4S through beam pair covers the greatest distance, while the O4P retro-reflective version reaches 22m. The powerful visible red light makes it easier to set up than one might think. The most remarkable performance though is reserved for the O4H diffuse unit; this will detect an object and tune out the background at a range of up to 2.6m. All these new units in the O4 range feature pushbutton setting for ease of set-up and to help maintain the IP67 seal. The pushbutton is also used to select light/dark operation and to operate the electronic lock facility. A range of mounting accessories including steel covers is offered to help install and protect the sensors. Operating on 10 to 36 V DC, the O4 range will switch a 200 mA load, PNP.
