Technical features

Radial mounting Hall effect speed sensors - Technical characteristics

Radially mounted Hall effect speed sensors detect the rotation of a through shaft onto which a tone wheel is keyed, with dimensions compatible with the centre hole.
This solution is ideal for those who have already prepared the housing for this type of mounting, and for those who need the through shaft to be free of bulk or obstructions at the closing flange.
The latter is the case, for example, when a motor brake or cooling fan needs to be fitted, as the shaft exit must be clear on both sides. It is a simple installation and replacement solution and the most economical.
Elen offers different mechanical and electronic configurations, with solutions both compatible and interchangeable with other manufacturers' products.

PERFORMING ELECTRONICS

- Power supply voltage: min 4.5V – max 30V
- Output signal: double - 2 square wave signals shifted by 90°
- Output in voltage: NPN, PNP, Open collector 
- Optional pull-up or pull-down resistor                                                                                                                                                                - Signal phase shift precision: ±40°/±30° (up to a minimum of ±15°)
- Zero speed (reading of the position even when the wheel is stationary)
- Operating frequency from 0Hz to 10,000Hz  ;
