FEATURES
• Quad Hall IC design minimizes mechanical stress effects
• Temperature-compensated magnetics help provide stable
operation over a wide temperature range of -40°C to 150°C
[-40°F to 302°F]
• Broad, inclusive supply voltage capability from 3.8 Vdc to
30 Vdc for application flexibility
• Digital, open collector sinking output for easy interfacing
with a variety of common electronic circuits
• High sensitivity versions available for potential applications
requiring high accuracy or wide gaps
• Bipolar, latching or unipolar magnetics
DESCRIPTION
The SS400 Series and SS500 Series are small and versatile
digital Hall-effect devices that are operated by the magnetic
field from a permanent magnet or an electromagnet, and
are designed to respond to alternating North and South
poles, or to a South pole only. They are available in bipolar,
latching or unipolar magnetics. On-board regulation provides
stable operation over a 3.8 Vdc to 30 Vdc supply voltage
range. These sensors are capable of continuous 20 mA
sinking output and may be cycled as high as 50 mA max.
The 3.8 V capability allows for use in many potential low
voltage applications. The digital, open collector sinking-type
output is easily interfaced with a wide variety of electronic
circuits. To provide reliable products and consistent quality,
the SS400 Series products are tested at both 25°C [75°F]
and 125°C [257°F]. All catalog listings are qualified for
operation up to 150°C [302°F]. For design flexibility, these
product are available in the following package styles:
• SS400 Series: Flat TO-92-style:
- SS4XX: Straight standard leads, bulk pack
- SS4XX-L: Straight long leads, bulk pack
- SS4XX-T2: Formed leads, ammopack tape-in-box
- SS4XX-T3: Straight standard leads, ammopack tape-in-box
- SS4XX-S: Surface mount, bulk pack
- SS4XX-SP: Surface mount, pocket tape and reel
SS500 Series: SOT-89B, pocket tape and reel
POTENTIAL APPLICATIONS
• Industrial: Speed and RPM (revolutions per minute) sensing,
tachometer, counter pickup, flow-rate sensing, brushless dc
(direct current) motor commutation, motor and fan control,
robotics control
• Transportation: Speed and RPM (revolutions per minute)
sensing, tachometer, counter pickup, motor and fan control,
electric window lift, convertible roof position
• Medical: Motor assemblies, medication dispensing control

1For supply voltages above 24 Vdc, a capacitor may be needed between the output and supply pins to ensure proper operation.
NOTICE
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 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.
