Technical Definitions
2-Wire Switch
3-Wire Switch
Unipolar
The switch turns to high current consumption with the magnetic south pole on the
branded side of the package and turns to
low consumption if the magnetic field is removed. The switch does not respond to the
magnetic north pole on the branded side.
The output turns low with the magnetic
south pole on the branded side of the package and turns high if the magnetic field is removed. The switch does not respond to the
magnetic north pole on the branded side.
Unipolar
Inverted
The switch turns to low current consumption with the magnetic south pole on the
branded side of the package and turns to
high consumption if the magnetic field is removed. The switch does not respond to the
magnetic north pole on the branded side.
The output turns high with the magnetic
south pole on the branded side of the package and turns low if the magnetic field is removed. The switch does not respond to the
magnetic north pole on the branded side.
Bipolar
(3-wire only)
The output turns low with the magnetic
south pole on the branded side of the package and turns high with the magnetic north
pole on the branded side. The output state is
not defined if the magnetic field is removed
again. Some switches will change the output state and some switches will not.
Latching
The switch turns to high current consumption with the magnetic south pole on the
branded side of the package and turns to
low consumption with the magnetic north
pole on the branded side. The current consumption does not change if the magnetic
field is removed. For changing the current
consumption, the opposite magnetic field
polarity must be applied.
The output turns low with the magnetic
south pole on the branded side of the package and turns high with the magnetic north
pole on the branded side. The output does
not change if the magnetic field is removed.
For changing the output state, the opposite
magnetic field polarity must be applied.
2-Wire
Switch
The current is monitored and the switch operates as indicated by the
type of switch. Current level is as speciified within the data sheet.
3-Wire
Switch
The voltage is monitored and the switch operates as indicated
according to the type of switch.

HAL 7xy dual Hall plate switches:
–– Highest switching accuracy
–– Motion direction and revolution counting by one IC
HAL 15xy single Hall plate swiches:
–– Price-attractive solution
–– High threshold accuracy thanks to lowest output jitter of
max. 0.72 µs (RMS)
–– ISO 26262 compliance for safety critical applications
Explanation: HAL 15xy counts the motor revolutions while the motors’
motion direction is determined by the control unit. Software algorithms
help to specify the accuracy of the motion direction.

BLDC Motor
Commutation
HAL 1502 or
HAL 1501
These Hall switches in SOT23 packages offer high
switching accuracy and low power consumption and
are used for the commutation of brushless DC motors
e.g. in power tools, washing machines, dish washers,
ventilation fans or electric bikes.
HAL 505
Rotation and
Speed Sensor
HAL 15xy
The HAL 15xy switch family enable short output
switching time and is used to detect or to control the
speed of motors, fans or liquid flow, e.g. in power
tools, home appliances, white goods (water delivery)
and wheel-speed in electric vehicles and electric bikes.
Proximity and
Position Sensor
HAL 15xy
The HAL 15xy switch family is offered in small packages and enable accurate switching points and a short
output refresh time. They are used as proximity sensors to detect the end-position to stop the motor or to
detect the absence or presence of material, e.g. rolling
shutter, or doors, or factory automation.
Geartooth Sensor
HAL 300,
HAL 320
Differential Hall switches can be used for speed measurement and position detection for RPM management, e.g. geartooth speed with back-bias magnet or
rotating multi-pole-ring in process automation control.
Door Lock
HAL 1565,
HAL 1564
These 2-wire Hall switches with high switching accuracy, low power consumption and integrated wirebreak detection can be used to detect if the door is
closed or open, e.g. in home appliances or white good
applications.
Magnetic Encoder
HAL 710,
HAL 730 (with
direction signal)
These Hall switches with two independent Hall plates
and outputs (quadrature interface, A&B) and constant
switching points can be used in linear encoder applications for position and direction detection, e.g. in factory robots or CNC machines, or for BDC motor control.
