Miniature sensors

09 August 2011

New varieties of miniature photoelectric sensors have been introduced by ifm electronic

The O7 range of miniature photoelectric sensors, from ifm electronic, is now available in NPN equivalents, in addition to the original PNP versions.

The sensor measures just 15 x 9 x 26mm, and the NPN version is also available in through beam, retroreflective and diffuse versions. The sender/receiver version reaches up to 1500mm in range, while the retroreflective will cover 1000mm. The diffuse units are all background-suppressed and offer ranges up to 30mm, 50mm and 100mm. In each case the unit is sealed and fixed in function. Light-on or dark-on versions are made available separately.

ifm electronic’s O7 photocell makes easy work of fine sensing tasks in confined spaces, with accurate and fast 1kHz sensing.

The visible red light makes these sensors simple to align, especially when used together with the wide range of fixing accessories available.

Connection is via the industry-standard M8 connector (three-pin) which is complemented by ifm’s own EVC range of socket leads and connecting jumper cables.
