An example of a
short traversing
system.
The traversing system consists of the linear positioner ("rail"), high-power stepper motor, motor control
system, computer interface, and position feedback system. The system is capable of traversing at speeds
of up to five feet (1524 mm) per second with a positioning repeatability better than 0.05 inches (1.27
mm). There are two limit switches and one home switch. All other positions can be achieved using
"steps" from the home switch, in inches, of measurements by designating the distance points along the
rail. The system also contains an emergency stop button. Communications are maintained with the
support unit over an RS-485 bus line. The support unit must be equipped with motor control capabilities
in order for the traversing system to operate.
A dual-position rail which allows only on-line and off-line positioning is also available.
Fixed Mounting Assembly
The fixed system provides a stationary mount for the sensor. This standard mount allows the sensor to
pivot around one axis. This allows you to align the sensing port perpendicular to the product.
Product Backing Strip
The product-backing strip provides a constant black background for product measurements. The length
of the backing strip will depend on the length of the system's rail. The system modifications required
add 1 inch (25.4 mm) to the overall length and 12 inches (294 mm) to the overall height of the system.
The backing strip rotates 180 degrees. When the backing strip is in place, the system J-box must be
installed off-line from the standard system position.
