Overview
The Dynapar HA525204B03S1 is a compact, reliable incremental encoder from the Series HA25 product line. The Dynapar brand Series H25 is a rugged, reliable and economical encoder for industrial motion applications. Packaged in an industry standard 2.5″ enclosure, the Series H25 offers a variety of mechanical options: servo or face mounting, and 1/4″ or 3/8″ shafts. This model is engineered for precise velocity and positioning measurement across automation, packaging, and motion control systems.
Key Features
- Unbreakable Metal Code Disk: Models with resolutions of 1024 or less are available with an unbreakable metal code disk that 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.
- Electrical Noise Protection: Protection against installation problems such as wiring errors prevents the encoder from damage, while immunity to electrical noise keeps the encoder signals intact.
- Optional NEMA 4/IP66 Sealing: A NEMA4 / IP66 sealing option protects against damage from contamination.
- Bidirectional operation with optional index pulse
- Multiple output configurations: Open Collector, Push-Pull, and Differential Line Driver
Technical Specifications
- Power Supply: 5 to 26 VDC (differential and push-pull at 80mA max.; open collector at 135mA max.)
- Output Current (Sink): 40mA sink at 0.5 VDC max.
- Bearing Load (radial/axial): 80 lbs for resolutions ≤1024 PPR; 40 lbs for resolutions >1024 PPR
