We will be closed from 24th December to 3rd January. However we will be dispatching orders throughout this period when the postal service is in operation.
We would like to wish all our customers, old and new, a very merry Christmas.
Yodel
Please note: Yodel is currently experiencing issues. Whilst the issue is ongoing, orders placed using this service will be dispatched via Evri or Royal Mail 48 hour service.
Allows for sensing of solid objects within a fixed range (adjustable with on-board potentiometer). Ideal for robotic applications.
Allows for sensing of solid objects within a fixed range (adjustable with on-board potentiometer). Ideal for robotic applications. Depending on the position of the potentiometers and the reflective surface type the sensing range is between 5 to 45cm (approx).
Supply Voltage: 3-6V
Digital Output: 0=object detected, 1=no object detected
Sensing Range: 5 to 45cm (approx - Please see note above)
