Cherry Sensor Products
Cherry speed and proximity sensors bring
tremendous freedom and unmatched
performance and reliability to your
consumer, commercial and industrial
equipment designs. Available in a variety
of standard sizes and configurations,
they serve as highly reliable replacements
for mechanical and optical components
in applications where performance and
reliability cannot be compromised, regard-
less of the operating environment. Dirt.
Grime. Heat. Even electrical interference.
Cherry speed
and proximity
sensors continue
to perform. And
with no moving
parts, they do so
with a virtually
infinite life
expectancy.
Our full line of speed
and proximity sensors
is divided into five
product series to ease
your selection process.
These product series,
detailed in this catalog,
are as follows:
•MP Series — Magnetic Proximity Sensors
•GS Series — Geartooth Speed
Sensor Assemblies
•SD Series — Geartooth Speed &
Direction Sensors
•VN Series — Vane Switches
•Miscellaneous Products & Accessories
Your Total Design Partner
To augment our line of standard sensor
products, Cherry also offers a wide variety
of packaging and wiring options to suit your
application. If your design calls for a product
we don’t currently offer as part of our
standard line, our in-house design staff will
work with you to develop a semi- or fully-
custom solution to your exact requirements.
Utilizing the latest design modeling and
rapid prototyping tools, we offer unequaled
product development assistance.
•In the initial design stages, our magnetic
modeling capabilities serve to verify
the design concept, while also helping
to obtain the optimal match of sensor
and magnet to your application.
•Once the design concept is approved,
we enter the physical prototyping
stage, using Pro Engineering solid
modeling software to create the
physical design and stereolythography
for rapid prototyping. Our in-house
plastic molding capabilities allow us
to provide prototype or production
parts in a very timely manner.
•Finally, our certified qualification lab
offers complete environmental testing,
product life testing and magnetic test
capabilities; the final step in readying
your sensor
solution for
final production.
World-Class
Manufacturing
Incorporating the
Kaizen philosophy
of continual improve-
ment, our Advanced
Manufacturing Group
has designed and
developed proprietary
assembly equipment
to provide you
unmatched production
flexibility. The capabilities of our ISO9001
Certified Manufacturing Center range from
plastic molding to automated surface mount
circuit board assembly.
From concept to completion, Cherry is your
source for Advanced Sensor Solutions.

Cherry sensor products
offer accurate and
reliable speed and
proximity sensing in
demanding environ-
ments, making them
ideal for industrial
control and factory
automation equipment.
The direct, digital output
offered by Cherry sensors
ties directly to micro-
processors used in advanced
consumer and commercial-
grade appliances.
Available in a variety
of configurations, all
Cherry sensors feature
rugged construction
and are immune to
dirt, water, oil and
other contaminants
typically found in
agricultural and other
heavy equipment
applications.
Solid State, magnetic
proximity sensors
in adjustable,
threaded barrels.

Some applications require the sensor have only two connections. To accommodate these
situations, several Cherry sensor assemblies are equipped with a 2-Wire interface (which
may be tested as shown in the block diagram). When the sensor is idle, current flowing
into the device via Pin 1 and out via Pin 3 is limited to that needed to power the Hall effect
device, a maximum of 6mA. When the sensor is active, the current flow will increase to
a minimum of 10mA as the Hall effect device turns on the programmable current
source. The voltage measured between the output and ground will therefore change
by a minimum of 0.4 Vdc. If Pin 3 is connected to a comparator, the comparator output will
switch in response to the change in voltage at Pin 3 of the sensor. Alternatively, Pin 3 can
be connected directly to ground and a load placed between Pin 1 and Vcc. In this case, Pin 1
becomes the output lead to be connected to a comparator.
Sourcing outputs are often used in positive logic applications, where a high signal is
required for an active state. Thus, sourcing outputs normally have current flowing out of
the device output lead when the device is active. Because a pull-down resistor is required
for proper operation, sourcing outputs are compatible with CMOS logic, but not with
TTL components. With the pull-down resistor connected as shown, the output will be
“pulled down” to ground when off and (approximately) to Vcc when on.
Recommended pull-down resistor values are as follows:
Sinking outputs are often used in negative logic applications, where a low signal is
required for an active state. Therefore, sinking outputs normally have current flowing
into the device output lead when the device is active. Also called “open collector outputs,”
sinking outputs are compatible with any logic family since a wide voltage range may be
used for Vcc. Furthermore, the voltage level used to power the Hall effect assembly may
differ from the pull-up resistor to which it is attached. The external pull-up resistor
connected between the output and Vcc is required for proper operation. With the resistor
connected as shown, the output will be ”pulled up” to Vcc when off and (approximately)
to ground when on.
Recommended pull-up resistor values are as follows:

Solid-State Speed Sensor
Proximity Sensor with Ring Magnet
Although commonly called a
geartooth sensor, a solid-state
speed sensor can detect the
motion of various ferrous
objects with some type of
discontinuous surface.
Examples of appropriate targets include:
■Sprockets
■Bolt Heads
■Roller Chains
■Cavities in a Smooth Surface
For best results, we recommend targets made
from low carbon cold rolled steel. Other factors
that influence sensor performance include
geartooth height and width, space between
teeth, shape of the teeth and thickness of the
target. As a general guideline, consider a target
with the following minimum parameters:
Cherry’s solid-state magnetic proximity
sensors also make excellent speed
sensors when coupled with a rotating
ring magnet. Advantages of this
approach include: lower sensor
cost, larger airgaps and absolute
zero-speed sensing.
