Introducing The HBA4

US Digital is pleased to announce the release of its latest absolute, blind hollow bore shaft encoder, the HBA4. This single turn absolute encoder provides 16-bits of resolution over 360 degrees of shaft rotation. The HBA4 is available with a 12mm or 0.500" diameter bore size with either a ball bearing or sleeve bushing bearing assembly and is sealed to an IP66 rating.

The absolute encoder slips over the shaft and is locked in place with a non-marring clamp mount. A flexible anti-rotation tether provides single point mounting for bolt circles ranging from 2.50" up to 5.00" in diameter and compensates for shaft run out. The HBA4 communicates serially to a host via the industry standard RS485 bus. HBA4 absolute encoders are used as azimuth and elevation position sensors in two axes tracking systems, commonly used in solar applications.

Typical Applications

  • Elevation control of heliostats and PV modules
  • Parabolic trough tracking feedback
  • Fresnel lens tracking feedback

HBA4 Product Features:

  • 16-bit single turn absolute resolution
  • Angular accuracy 0.07°
  • Hollow bore with tether mount provides run out compliance
  • Programmable resolution, zero location, CW/CCW direction
  • Ball bearing or sleeve bushing rotating assembly
  • Non-marring clamp mount
  • IP66 rating
  • -25 C to 85 C operating temperature rating
  • Aggressive pricing and two year warranty

Introducing The T7

T7US Digital is proud to introduce our latest innovation: the T7 absolute inclinometer. The T7 is an absolute inclinometer utilizing a unique solid-state sensor to give high accuracy tilt readings over a full 360 degree range.

Typical Applications

  • Elevation control of heliostats and PV modules
  • Parabolic trough tracking feedback
  • Fresnel lens tracking feedback

Product Features

  • Full 360 degree range, single axis
  • ±0.1 degree accuracy from 0C to 70C
  • 0.01 degree resolution
  • Sealed against dust and water (IP-67 rated)
  • RS232 version allows up to 15 T7s on 100 feet of cable
  • -10 to 70 Degrees C Operating Temperature
  • US Digital CAN version allows up to 64 T7s to be networked
  • USD-CAN supports 700 feet (213 m) maximum cable length

The T7 is available with either a RS232 or USD-CAN interface. The RS232 version supports up to fifteen T7s on a single cable. US Digital's CAN protocol allows a network of up to sixty-four T7s to be connected to a single host. Power for each T7 is supplied over the network cable. The host accesses the T7-CANs through US Digital's low cost CANA-232/CANA-485 adapter module. This module allows the host to access each T7 on the network using simple serial port commands. A Windows demo application is provided for displaying the angles and temperature as well as setting operating modes, orientation, zero position, damping / averaging time, direction, and more for every T7 on the network. Additionally, a Windows DLL gives the user a set of simple functions to read and write data to a network of T7s.

T7 pricing starts at $225.00 for single units and $205.00 for 10 units. US Digital products are sold direct for easy ordering and fast shipment.

Introducing The HBA2

HBA2 US Digital is pleased to announce the release of its latest Absolute Encoder hollow bore encoder, the HBA2. The HBA2 is based upon US Digital’s very successful 12 bit A2 absolute encoder platform which has been incorporated into a large bore bearing assembly with a tether anti-rotation mounting arm. The large bore design allows the encoder to be easily attached to shaft diameters ranging from 6mm up to 0.750" and tether mount bolt circles of 2.50" up to 5.00".

The hollow bore and tether design replaces the traditional method of using a flexible coupling and subsequent encoder housing support systems of the past. Now with the HBA2 encoder, providing absolute position of a rotating shaft becomes a simple task.

HBA2 pricing starts at $383.00 for single units and is $279.21 for 100 units. US Digital products are sold direct for easy ordering and fast delivery.

Product Features

  • 12 bit single turn absolute encoder
  • Hollow bore design tolerates run-out
  • Programmable zero location
  • Low cost
  • Industrial duty 6805 series bearings
  • Analog output option available
  • Programmable resolution
  • Programmable CW or CCW count direction
  • -40 to 100 deg C operating temperature
  • Two year warranty

Introducing The E8P

E8P OEM Optical Kit EncoderUS Digital is pleased to announce the release of its latest encoder in a line of high performance, low cost solutions for motor feedback applications: the model E8P. The E8P is specifically designed to fit on NEMA Size 11 motor frames and provides incremental encoder feedback information.

The E8P’s unique collet style, push on hubdisk assembly eliminates the need to rely upon the set screw to retain the code wheel to a shaft. Standard bore sizes range from 3mm up to 7mm; single ended and differential outputs are readily available. If you have a size 11 stepper motor which requires encoder feedback, the E8P is the ideal product for your application.

The E8P pricing starts at $33.95 for quantity 1 and is $16.95 at 100 units. US Digital encoders are available to ship the same day if the order is received before 1:00pm Pacific Time.

Introducing the USB4

photo.jpgUS Digital is proud to introduce our latest USB interface product, the USB4. The USB4 is a high speed USB data acquisition device with multiple input and output types along with advanced triggering functions.

USB4 Product Features:

  • Four Incremental Encoder Inputs
  • Eight Digital Inputs
  • Four 12-Bit Analog Input Channels
  • Eight Digital Outputs
  • Four 12-Bit Analog Output Channels
  • High Speed USB 2.0 Interface
  • 32 MByte FIFO
  • Comprehensive Programming Information and Examples

All communication between the USB4 and the host PC is sent over a USB interface. The USB4 is compatible with USB 2.0 hubs, allowing multiple USB4 units to be used with a single PC. To handle continuous streaming of data over USB to the host PC, the USB4 has a 32Mbyte FIFO to buffer the captured data when the host PC or USB bus is busy.

US Digital provides a CD with all the software and documentation needed to use the USB4. A library with a detailed Application Programming Interface is provided so users can develop their own applications; additionally, the CD provides several examples that demonstrate how to use the FIFO, how to log data, etc. For programmers who prefer lower level control, a register based interface and documentation is provided so the USB4's internal registers can be configured at the bit level.

The USB4 is available to ship the same day as ordered if the order is received before 1:00 P.M. Pacific time. The USB4 is covered by US Digital's two year warranty against defects in materials and workmanship.
