HR 25 Encoders
Rugged,
Reliable and Economical Encoders For Industrial Motion Applications
Heavy
Duty Size 25 (2.5") Encoder
Unbreakable code disk
Complete
Electrical Protection and Noise Immunity
Environmentally
Sealed To NEMA4/IP66
Up To
1024 PPR With Optional Marker Pulse
| The
unbreakable code disk meets the demands of the most severe shock and
vibration generating processes; and a long life 80 pound (352 N.)
bearing that keeps tough loads from disrupting internal alignment,
avoiding failure due to the disk "crashes" so typical in
competitive encoders. Protection against installation problems such as
wiring errors prevents the encoder from damage, while immunity to
electrical noise keeps the encoder signals intact. A NEMA4 IP66
sealing option protects against damage from contamination.
Packaged in
an industry standard 2.5" enclosure, the Series HR25 offers a
variety of mechanical options: servo or face mounting, and 1/4"
or 3/8" shafts. Electrical options include: resolutions from 1 to
1024 pulses/ revolution; bidirectional operation with optional index;
single ended open collector or push-pull outputs, or differential line
drivers; and a connector or cable exit terminations.
The Series
HR25 utilizes the latest technology optical emitters and sensors,
surface mount assembly and precisely fabricated metal components to
deliver a high reliability and performance in a compact and economical
package.
