  3. 3. Ver 1.0 3 Joral designs and manufactures Shafted, and Non Shafted magnetic encoders, position sensors, and Tilt Sensors. Joral has been the suppler for CAT timber harvesting computers for 15 years, during a customer visit in 2004, an engineer asked if we could design a better encoder. The current product they were using had a life in the field of several months. Our first shafted encoder product was installed on a harvest head in January of 2005. During 2007 we invented the Non Contact Encoder in the Hockey Puck format, and applied for a patent on the design. We named it that first because of its unique shape, but also because to prove its ruggedness, we played hockey, using the encoder as the puck. Higher pulse rate encoders, the 18mm form factor, and 30 mm form factor followed. Our latest market innovation is the field programmable magnetic encoder requiring only a simple push of a button and turn of the shaft. Our first shafted encoders were (and still are) installed on timber harvesting heads. We have encoders on, or are the OEM supplier for manufactures such as CAT, John Deere, Logmax, TigerCat, Waratah, etc. Our first Hockey Puck encoders were installed on a ship laying undersea cable, watching the spools unreel the cable. Since then Joral non contact encoders have been installed in a myriad of situations were traditional encoders have failed due to environmental conditions. Including such applications as cement trucks, car washes, logging machines, sewer cleaning machines and conveyors on bottling lines. All Joral devices are designed from the end users point of view. Diagnostic LEDs, total encapsulation, wide operating voltage range. While standard products are our main focus, we also design custom and embedded sensors for OEM applications.
  4. 4. Ver 1.0 4 Non Contact Encoders and Rotation Sensors A Bi-Polar (N/S across the face) magnet is mounted an the axis of the rotating shaft. The magnet is referred to as the “Application Magnet”. The Sensor is mounted so that the active end has clear view if the “Application Magnet” Sense distance is dependent on installation variable, Rotation Speed, Application magnet, Shaft Acceleration etc. Sense distance .1 to .5 inches is typical with over 2 inches possible. Sensor and Application magnet may be axially misaligned.
  5. 5. Ver 1.0 5 What’s The Magic? All Sensor based Hall encoders have the same basic design. A sensor chip with multiple Hall elements (4 to 6) has a rare earth magnet precisely located on its center axis. As the magnet spins, the Hall sensors detect the magnetic field impressed upon each element. Since the magnet is diametrically magnetized, each sensor sees a slightly different N/S force. A DSP then compares the strengths and calculates the absolute magnet position. The internal magnet is held within .1 mm of both the sensor center axis, and the Z distance. The Joral difference is that the sensor magnet is contained inside the encoder. In a specially machined cavity, suspended on ceramic bearings. The “application magnet” is used to spin the “sensor magnet” inside the encoder.
  6. 6. Output Waves & Signals Outputs For Different Applications Joral Proxcoders provide a full range of output signals. Both incremental and absolute signals are available. Ver 1.0 6 Quadrature with marker index pulse data channels show motion and direction. Step and Direction – The step wire pulses to indicate shaft motion, the direction wire indicates direction of shaft rotation – Recommended for PLC connection SSI interface reports absolute encoder position as a serial data signal for connection to PLC or microprocessor Analog reports shaft position as a variable voltage. 0 to VDC or 0 to 5VDC are both available. PWM output is perfect for connection to a microprocessor. Each bit is represented by a 1us of on time. Encoder angle is calculated by the ratio of on time to total signal time.

  11. 11. Ver 1.0 11 J1939 for Mobile Markets Developed by the Society of Automotive Engineers (SAE) J1939 is the preferred CAN communication method for equipment used in a wide range of industries. Forestry , agriculture, construction, and fire/rescue use J1939 to communicate vital machine parameters to the controlling computer. J1939 protocol that defines the format of the message “nodes” devices on the machine. - The JORAL J1939 encoders transmit instantaneous position information, and average RPM in the standard communication message. An external programming resistor may be used to set the device address so multiple encoders may reside on a single bus. Connects to Parker IQAN, IFM Eefector, Danfoss Plus One and a host of other J1939 platforms. 8192 Absolute Position Position and RPM Output Cable or M12 Connector 30mm or 58mm shell Sealed with LED’s Addressable
  12. 12. Ver 1.0 12 Absolute SSI Interface SSI “Synchronous Serial Interface is an industry stand for serial communication interface between encoders and host computers of PLC’s. The encoders absolute position number is transmitted in time as a series of on/off pulses. The timing is controlled by the clock pulse. The SSI interface uses a CLOCK and DATA (optionally an ENCODER SELECT). SSI interface for PLC or Microprocessor connection A 13 bit encoder would require 14 wires to send the position information to a host computer if the connection were in parallel. The serial SSI connection only requires 4 wires, and may be transmitted thousands of feet.
