Datasheet
FEATURES
• Small, flat TO-92-style package size allows for a compact PC
board layout
• Current consumption of only 5 mA max at 4.5 Vdc for energy
efficiency
• Sensitive, bipolar magnetics respond to alternating North
and South poles, making these products suited for speed
sensing and RPM measurement
• High speed: operates from 0 kHz to over 100 kHz
• Built-in pull-up resistor can easily interface with common
electronic circuits without adding external components,
helping to reduce total system cost
DESCRIPTION
These small and versatile digital Hall-effect devices are
operated by the magnetic field from a permanent magnet or
an electromagnet, and are designed to respond to alternating
North and South poles. The built-in regulator provides
enhanced stability of operation from over a 4.5 Vdc to 24
Vdc supply voltage range, and internal circuitry is designed
to prevent sensor damage in case the supply voltage polarity
is accidentally reversed. The open-collector sinking output
voltage is easily interfaced with a wide variety of electronic
circuits. Both products are designed for high volume
applications. The SS40F is factory tested at 25°C [77°F] and
the SS40AF is factory tested at both 25°C [77°F] and 125°C
[257°F]. These products are available in a flat TO-92-style
package with straight leads in bulk packaging.
• RoHS-compliant materials meet Directive 2002/95/EC
POTENTIAL APPLICATIONS
• Commercial: Door or lid closure detection in appliances,
speed and RPM (revolutions per minute) sensing in fitness
equipment, damper or valve position control in HVAC
(heating, ventilation, and air conditioning) equipment, flowrate sensing in appliances and water softeners, printer head
position sensing
• Industrial: Flow rate sensing in industrial processes, robotic
control (cylinder position monitoring), float-based fluid level
sensing
• Transportation: Brushless dc motor commutation,
electronic window lift, anti-pinch power window systems,
vehicle convertible roof position
• Medical: Medical equipment using electric motors

These Hall-effect sensor ICs may have
an initial output in either the ON or OFF
state if powered up with an applied
magnetic field in the differential zone
(applied magnetic field >Brp and <Bop).
Honeywell recommends allowing 10 us
after supply voltage has reached 4.5 V
for the output voltage to stabilize.

NOTICE
The magnetic field strength (Gauss)
required to cause the switch to
change state (operate and release)
will be as specified in the magnetic
characteristics. To test the switch
against the specified limits, the switch
must be placed in a uniform magnetic
field.
