• RoHS-compliant material meets directive 2002/95
POTENTIAL APPLICATIONS
Transportation
• Speed and RPM sensing
• Tachometer, counter pickup
DESCRIPTION
• Motor and fan control
The SS361RT and SS461R are small, versatile, digital Hall-
• Electronic window lift
effect sensor ICs that are operated by the magnetic field from
• Convertible roof position
a permanent magnet or an electromagnet, and designed to
• Automotive transmission position
respond to alternating North and South poles. The SS361RT is
turned on by a North pole while the SS461R is turned on by a
South pole.
These latching digital Hall-effect sensor ICs have enhanced
sensitivity of only 50 G typical, at 25°C [77 °F] that often allows
for the use of less expensive magnets or wider air gaps. They
offer a robust IC design with reverse polarity protection and

• Tachometer, counter pickup
• Flow-rate sensing
• Brushless dc motor commutation
• Motor and fan control
• Robotics control
150 °C [302 °F] capability.
These product are available in two package styles:
• SS361RT: Subminiature SOT-23 surface-mount package on
pocket tape and reel which allows for compact design with
automated component placement.
• SS461R: Flat TO-92-style package with straight leads in bulk
packaging which allows for a compact PC board layout.
PORTFOLIO

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 μs after supply
voltage has reached 5 V (SS361RT) or
3 V (SS461R) for the output voltage to
stabilize.

NOTICE
The magnetic field strength (Gauss)
required to cause the switch to change

specified in the magnetic characteristics.
To test the switch against the specified
limits, the switch must be placed in a
uniform magnetic field.

NOTICE
Absolute maximum ratings are the extreme limits the device will momentarily withstand without damage to the device. Electrical
