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
At a glance
• Extremely rugged, tried-and-tested
• Mechanical interface: through hollow
• Zero-set and preset functions via
absolute multiturn encoder with a
resolution of up to 26 bits
shaft with shallow installation depth
hardware or software
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
climate uctuations
• Electrical interface: SSI with gray or
binary code type
• Electronically adjustable, congurable
resolution
• Magnetic scanning

Your benets
• 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
