Datasheet
FEATURES
• Small, leaded, flat TO-92-style package allows for a compact
PCB layout
• Wide operating voltage range of 4.5 Vdc to 24 Vdc allows
these sensors to be used in a variety of applications
• Current consumption of only 5 mA max. at 4.5 Vdc for
energy efficiency
• Bipolar magnetics for ring magnet applications with
alternating North and South poles
• Robust design: Will operate up to 150°C [302°F]
• RoHS-compliant materials meet Directive 2002/95/EC
POTENTIAL APPLICATIONS
DESCRIPTION
• 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
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 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. The SS41 is tested at both 25°C [77°F] and 125°C
[257°F]. For design flexibility, these product are available in
the following flat TO-92 package styles:
• 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
