ATM90 SSI ABSOLUTE ENCODERS

RELIABLE, ESTABLISHED, AND MODULAR

Product description

The ATM90 with SSI data interface
complements the through hollow shaft
variants in the ATM60 product family.
The ATM90 operates reliably even under
harsh ambient conditions. Its rugged
mechanical design ensures maximum re­liability and a long service life. Magnetic
singleturn scanning allows a maximum
resolution of up to 13 bits within one
revolution. The number of revolutions,
maximum of 13 bit, is output and

recorded using a mechanical and almost
completely wear-free transmission. This
means that the ATM90 can be operated
without a battery. A shallow installation
depth of 60 mm combined with high
shock and vibration resistance enable
the ATM90 to be used in applications
with high mechanical stress and distinct

Your benets

• Fewer variants are required since one

freely programmable encoder offers
all singleturn and multiturn resolu­tions

• Easy setup due to various electrical

connection adapters (cable, M23)

• Maintenance-free encoder, long

service life

• Quick commissioning using the zero

set/preset function either at the press
of the button on the device or via
software

• Increased productivity due to highly

reliable shock and vibration resis­tance

• Worldwide availability and service

ensure quick and reliable customer
service

V/¯R This input programs the counting direction for the encoder. When it is not connected, this input is set to HIGH. If the encoder

shaft is rotated clockwise (to the right) as viewed when facing the shaft, it counts in ascending order. If it should count in as­cending order when the shaft is rotated counterclockwise (to the left), then this connection must be permanently set to LOW
level (GND).

SET This input is for electronic zeroing. If the SET cable is set to U

for more than 100 ms, the mechanical position corresponds to

S

the O value, i.e., the predetermined SET value.
