Mounting the device
Device has 2x 3.1mm diameter mounting holes, suitable for M3 screws. The mounting hole pads are 5.6mm in diameter. Design any mounting posts to be no greater than 5.6mm in diameter.
Encoder Target
AS5311 magnetic target
The AS5311 returns the position of a multi-pole magnetic strip mounted to a moving structure at a fixed distance from the surface of the sensor. The AS5311 is capable of both linear motion sensing via multi-pole magnetic strip and off-axis rotational motion sensing via a multi-pole magnetic ring.
Both linear and ring magnetic targets should have the following properties:
| Pole length | 1mm |
| Pole-pair length | 2mm |
| Magnet type | plastic or rubber bonded ferrite or NdFeB |
| Required magnetic field strength | 10mT - 40mT at the die's surface |
| Suggested vertical gap | 0.3mm Package to magnet surface, depending on magnetic field strength |
For further detailed information consult the AustriaMicroSystem AS5311 datasheet.
