Mechanical Position Feedback
Low Cost Set of Two Transponders $147 in hundreds
Size (50 x 50 x 23 mm)

The HXP series is commonly applied in sets of two where one unit transponds to another the signaling is modulated and robust. It is useful as an industrial or general purpose mechanical feed back. If you don't find a device that suits your application, let us know we can change the parameters.

ABSOLUTE MAXIMUM RATINGS
Ambient temperature during operation	-40°C to +125°C
Storage temperature	-65°C to +150°C
Voltage on the Brown wire	0V to 5.3Volts
Voltage on the Red wire with respect to the black wire	8 to 16 Volts DC
Maximum current out of Black Wire	300 mA
Maximum current into the Red Wire	250 mA

Wire Configuration
Wire Color	Function
Red	Vsupply in 8 to 16 V
Brown	Variable voltage (max drive capacity 5mA)
Black	Gnd (return)

The illustration below shows how the HXP converter series can be applied. The brown wire is connected to a volt meter.

In case of the Distance to Voltage converters the voltage is proportional to the distance or

Voltage (brown wire) = (Vcc * D) / (Max Distance)

2D and 3D multipoint example

The illustration below shows one possible situation where an object is tracked on a XY plane. Only two distances are really needed say D1 and D2 to get 2 dimensional coordinates. But the setup shown below will work well with transceivers on all sides. And if one more transceiver was added on top, 3D XYZ coordinates become available. Object may be moving with respect to fixed transponders 0 or both may be moving relative to each other, transponder0 can also be placed on the object so the object can know its own position.
