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.

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.

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.

Joral Proxcoders provide a full range
of output signals. Both incremental
and absolute signals are available.

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.

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.

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.
