Rugged impedance differential transducer for motion control uses introduced by Kaman Precision Products

MIDDLETOWN, Conn. – The Measuring Division of Kaman Precision Products Inc. in Middletown, Conn., is introducing the DIT-5200L non-contact impedance differential transducer for servo control feedback, stage positioning, angular displacement indication, X-Y orbit position feedback, and stylus position.

The motion control transducer offers differential for common mode rejection, and is capable of subnanometer resolution with high sensitivity and linearity to 0.1 percent full range.

The DIT-5200L is a commercially based analog product built to IPC A-160 Class 3 standards. Depending on the program requirements, it also offers the opportunity for commercial-off-the-shelf (COTS) upscreening. The I/O is on a 9-pin mini-D connector, and the input power connections are reverse voltage protected.

The rugged product's signal conditioning electronics are packaged in a die-cast aluminum box with MCX style sensor connections, and the overall package size is 7.7 cubic inches. The product is CE marked when purchased in the original enclosure.

The electronics also can come as a bare printed circuit board for installation inside the user's enclosure, and custom configurations can be designed for OEM application requirements upon request.

The product features high precision eddy current balanced bridge technology. In an eddy current differential system, the two coils in the inductive bridge are housed in two separate sensors. Rather than one active coil and one reference coil, both sensors contain active coils. These two sensors are typically placed on opposite sides of either the target or the target pivot point.
