MEHR 25 C optical incremental hollow shaft encoder

MEHR 25 C Optical Incremental Hollow Shaft Encoder

Compact High-Resolution Motion Feedback

The PWB MEHR 25 C is a high-performance optical incremental hollow shaft encoder engineered for applications requiring accurate speed and position feedback in limited installation spaces. Its compact 25 mm diameter housing allows seamless integration into servo motors and automated machinery without sacrificing performance.

Using precision optical sensing technology, the encoder delivers stable incremental signals with differential TTL outputs and an integrated index pulse for accurate motion control. Available with resolutions up to 12,000 counts per revolution (CPR), the MEHR 25 C is suitable for demanding positioning applications requiring excellent repeatability and reliable operation.

Designed for easy installation and long-term durability, the encoder features IP55 protection, a 5 VDC supply, and operates in temperatures from -20°C to +85°C, making it suitable for a wide range of industrial environments.
