KD-5100+
The KD-5100+ is an upgraded higher reliability version of Kaman’s proven KD-5100 measuring system and utilizes the identical hybrid microcircuit. The KD-5100+ incorporates upgrades to: circuit layout, ground connections, and sensor connectors, and adds higher reliability diodes and capacitors. The KD-5100+ retains the performance of the KD-5100 system.
Two precisely matched sensors of a measuring channel are positioned opposite each other on the back of a Fast Steering Mirror (FSM) in two coordinate axes. As the FSM actuators drive the mirror about the center flexure, the mirror moves away from one sensor of an axis and toward the other sensor by an equal amount. The KD-5100+ output signal is used to actively control mirror position.
Applications:
• Laser Communications
• Satellites and Ground Stations
• Directed Energy: Ground, Shipboard, and Airborne
• Image Stabilization Systems

Many options are available to customize a standard system to meet the exact needs of the application. The most popular are:
Most sensors can handle longer cable lengths, although increasing the cable length can and will affect some performance specifications. Shorter than standard cable lengths are also available. Call an apps engineer to discuss your particular requirements.
Many sensors come with integral sensor cables. Routing this cable in some applications is difficult and something you only want to do once. Including an in-line connector splice in the cable, near the sensor itself, allows for easy sensor replacement should the need arise.
Some applications pass the sensor through a pressure boundary, most commonly a vacuum chamber wall. We offer an in-line hermetic bulkhead splice for these applications.
Standard published ranges are based on meeting a set of performance specs. Custom calibrations are possible to meet specific application needs. Contact a Kaman applications engineer if a custom calibration is desired.
Unless otherwise specified, nonferrous systems will be calibrated with an aluminum target. If your target material is significantly different in conductivity and/or permeability it may be best to calibrate using the same material as your target.
