Many companies are addressing the need for smaller sensors. Check out: It’s a Small World: Sensing in Tight Spaces. However, Balluff has a particularly strong effort in this area with miniature sensors that use inductive, photoelectric, magnetic, capacitive and ultrasonic operating principles. In addition to increased design freedom from limited space constraints, the sensors do not sacrifice performance. Compact inductive couplers, space-saving I/O modules and RFID in miniature versions are available for each sensor technology. An example of small size is the shortest inductive M12 sensor in the world that has a length of 12 or 17 mm and can be mounted flush or non-flush.
