The FVDK 13 Series fiber optic photoelectric sensors from Baumer Electric Ltd. are suitable for applications where sensing objects as small as 0.1 mm is required. The miniaturized sensing head can be used in extremely confined areas, while a visible red beam functions as an alignment aid to simplify installation. Cables can be cut to length using a Baumer-supplied cutting tool. The sensors come in reflective and through-beam configurations, with a maximum sensing range of 200 mm. A coarse and fine sensitivity adjustment is available, as is a light/dark operating switch.
