New Interface Offers Directional Control, a Pushbutton and Momentary Rotation

Grayhill, Inc. has introduced the compact Series 67B Joystick, a Hall-Effect joystick with a pushbutton and momentary knob rotation for additional interface options. The joystick travels 20 degrees in each X and Y direction as well as momentary rotation around the Z axis. With a 32mm diameter and requiring just 16mm behind panel depth, the new 67B is the smallest joystick to offer this many functions.

A hall-effect sensor provides contactless operation, facilitating a long operational life of over 1 million cycles.  The hall-effect sensor magnetically detects the shaft position anywhere within its 20-degree field of travel.  The on-board micro-controller then produces X,Y coordinates in a range from 0 at center to 50 at the extreme periphery for digital output.  It also conserves power by operating at 3mA max, with a built-in sleep mode of only 0.1mA max.

Output is via a built in micro-controller for I2C interface. I2C is a simple and flexible interface bus for communication with other digital devices. Most other joysticks of this size only offer an analog output.

The Series 67B Joystick is designed for panel mount applications where space is limited. Its integral mounting flange has 4 threaded mounting holes in a 28mm square.  This compact joystick can provide precise cursor control where other pointing devices are impractical, such as on medical electronics, work vehicles and industrial or robotic control.

Grayhill's proven technology and quality systems ensure superior performance with minimized costs.  The 67B has been fully-tested in ISO/IEC 17025 labs to achieve electrical and environmental specs, including:

  • Environmental Seal: IP67 with optional sealing boot
  • Operating Temperature Range: -40°C to +85°C

Part number 67B-RA-3C-S-04C is a full feature standard version with 2-axes joystick, momentary rotation, center pushbutton, a sealing boot, 3.3V input and I2C output via a 4 inch cable and connector.  Connection options include a 0.05-inch centerline pin header or a connector and cable assembly.  A standard knob is offered as part: 677702. The standard version may be purchased in minimum orders of $500, with lower quantities available through Grayhill authorized distributors.
