Series 605 Versatile ADTs

Product catalog summary

Overview: The Model 0605 is an absolute rotary position transducer that uses differential capacitance for integration into analog or digital systems. It includes internal voltage regulation and a factory-set full-scale output, allowing for easy unit interchangeability without recalibration. The model offers eight full-scale ranges (12° to 300°), five output types, and various termination options, resulting in over 640 configurations. Custom ranges and outputs are available for specific applications.

Key Features:

Ranges from 12° to 300°
Non-linearity less than 0.25%
3 KHz Frequency Response
DC Voltage/4-20 mA Output

Specifications:

Mechanical: Infinite resolution, maximum weight of 6 oz, and specific torque requirements.
Temperature: Operating range from 32°F to 158°F, with optional extended range.
Electrical: Voltage input from ±14.5 to ±26 VDC, maximum current of 40 mA, and short circuit protection.

Inductive Technology: Discusses the effects of altering magnetic field paths, exposure to electromagnetic fields, and temperature on magnet performance. ALNICO and CUNIFE magnets are highlighted for their sensitivity and ruggedness.

Common Questions:

Output can be read with instruments capable of reading DC voltages.
Output scaling is possible using a voltage divider.
No excitation voltage is needed as units generate DC voltage output.
Velocity thresholds are discussed, with a maximum permissible generated voltage of 500 VDC.
Magnet material selection depends on application needs, with ALNICO offering high sensitivity and CUNIFE providing ruggedness.

Ordering Information: Includes notes on rotation direction, temperature range limitations, and available options. A dimensional drawing is provided for reference.

Connector Specifications: Describes a 5-pin connector with specific dimensions and threading details. The mating connector has a thread size of 8-32 Thd x .375 (9.52) deep, with three holes equally spaced on a 1.100 (27.9) ±.005 (.13) diameter bolt circle. Various dimensions are provided in inches and millimeters.

Electrical Connections: The connector pinout is detailed with color-coded cables for different electrical functions: +V in (Red), Power Ground (Green*), -V in (Black), Signal (White), and Signal Ground (Shield*). The asterisk indicates internal connections to the shaft.

Transducer Technology: Trans-Tek manufactures Linear Velocity Transducers (LVTs) using inductive technology. The principle involves moving a magnet through a coil to induce voltage, proportional to the magnet's velocity and field strength. The coil is divided into two sections to prevent voltage cancellation, with the coils connected in series-aiding for DC voltage output.

Coil Configurations: For series operation, blue and green leads are tied together, with output from black and red leads, maximizing sensitivity and noise immunity. Parallel operation involves tying black and blue leads together, and green and red leads together, reducing sensitivity and source impedance, beneficial for high-speed applications and compatibility with low input impedance electronics.

Magnet Materials: Two magnetic materials are used: ALNICO, known for high sensitivity and brittleness, and CUNIFE, noted for ruggedness and lower sensitivity. Proper care involves maintaining molecular alignment and magnetic field integrity.

Model 605 General Purpose ADTs The Model 0605 is an absolute rotary position transducer based upon differential capacitance. It has been designed to provide a simple means of inputting angular position into analog or digital systems. Internal voltage regulation along with a factory set full scale output allows the direct interchanging of units without system recalibration. The Model 0605 allows great flexibility in supporting individual customer's requirements. With eight different full scale ranges from 12° to 300°, five different outputs, termination choices, and other options, there are over 640 available versions of this design. For each range the user can be supplied with one of five specified outputs. For unique applications, when the normal configurations are not suitable, custom ranges or outputs can be specified.
