Series HR25 Incremental Encoders
- Ultra-reliable, 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
Overview / Design Principle:
The unbreakable code disk meets the demands of the most severe shock and vibration generating processes; and long life bearings that keep 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 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 high reliability and performance in a compact and economical package.
