The new compact Grayhill Series 67A Joystick, a Hall-Effect joystick with a built in micro-controller for I2C interface is now available in the UK from EAO - the expert partner for Human Machine Interfaces.
I2C is a simple and flexible interface bus for communication with other digital devices. More common in larger joysticks, Series 67A is the first to offer digital output from a joystick with a 28mm tall bat-handle, requiring just 18mm of behind panel depth.
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 80 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.
The 67A Joystick is designed for panel mount applications where space is limited. Its integral mounting flange has 4 counterbore mounting holes in a 25.4mm square. This compact joystick can provide precise cursor control where other pointing devices are impractical, such as on test and measurement equipment or medical electronics. Other applications include CNC positioning, industrial control or robotic control.
Grayhill's proven technology and quality systems ensure superior performance with minimized costs. The 67A has been fully-tested in ISO/IEC 17025 labs to achieve electrical and environmental specs, including:
Environmental Seal: IP67
Operating Temperature Range: -40°C to +85°C
Initially, one standard version is available with 2-axes, 3.3V input and I2C output. Connection options include a 0.05-inch pitch pin header or a connector and cable assembly.
