ifm electronic is launching the O7 series miniature photoelectric sensors for applications where small objects must be detected accurately from a distance - but where space is the problem.
The low-profile O7 opto sensors have overall dimensions of 15 x 20 x 9mm, and the sensing axis is along the front-to-back dimension of 9mm.
A small visible light spot enables small objects to be detected with high precision. With their fixed setting, the sensors are ready for operation immediately after installation.
O7 sensors are available from ifm electronic as diffuse reflection sensors with background suppression, retro-reflective sensors with polarisation filter or as through-beam transmitters and receivers. Background-suppressed diffuse variants are offered with three different fixed ranges of 30mm, 50mm, and 100mm. Retroreflective units work up to 1m, and 1.5m is achieved with the separate transmitter/receiver through-beam. In each case the light/dark switching function is provided by the unit selection. The light spot diameter of just 2.5mm in some units means it is almost laser-like without the cost or safety concerns of a laser.
Reliable operation is ensured in industrial conditions with functions guaranteed from -25 to 60degC, and the O7 photoelectric sensors protected to IP65.
Connection to the sensor is made using a standard M8 connector on a short 200mm cable for ease of access. A wide range of accessories ensures quick and flexible integration into the system, as well as quick installation and alignment.
