4. Type Description

4.1. HAL 710, HAL 730

The types differ according to the behavior of the Direc-

tion Output (see Section 1.2. on page 4).

Magnetic Features

– typical BON: 14.9 mT at room temperature

– typical BOFF: −14.9 mT at room temperature

– temperature coefficient of −2000 ppm/K in all mag-

netic characteristics

– operation with static magnetic fields and dynamic

magnetic fields up to 10 kHz

Positive flux density values refer to magnetic south

pole at the branded side of the package.

Applications

The HAL 710 and the HAL 730 are the optimal sen-

sors for position−control applications with direction

detection and alternating magnetic signals such as:

– multipole magnet applications,

– rotating speed and direction measurement,

position tracking (active targets), and

– window lifters.
