Inductive Displacement Sensors

Balluff offers Inductive Displacement Sensors, Series BIW. It is an analog system with a sampling rate of 20 kHz and resolution and repeat accuracy in the micrometer range. It is also immune to shock, vibration and ambient magnetic fields. It utilizes a new, patented operating principle for sensing position without contact. It contains a sender/ receiver element and a tuned circuit enclosed in an extruded aluminum housing. The tuned circuit is attached to an articulated slide connected to the moving member of the machine whose position needs to be known. The principle of operation is simple: The sender component of the sensor excites the tuned circuit at a sampling rate of 20 kHz and couples a signal representing the current position into the receiver element. The position is then available as an absolute output signal with selectable rising or falling output slope. It is ideal in metal and plastic forming and bending machines. The fast sampling rate of 20 kHz improves product quality especially when sensing rapid, dynamic motion such as punching or in the injection unit of a plastic injection-molding machine. A wide range of accessories includes connectors, mounting and fastening elements and display units.
