Ultra small digital output Hall effect joystick

The new compact Grayhill Series 67A Joystick, a Hall effect joystick with a built in microcontroller for I2C interface, is now available in the UK from human machine interface specialist EAO.

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 1million cycles. The Hall effect sensor magnetically detects the shaft position anywhere within its 20 degree field of travel. The on board microcontroller then produces X,Y coordinates in a range from 0 at centre 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 four 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. E: sales.euk@eao.com T: 01444 236000
