Product Description
BEI Sensors EM-DR1-DB4-5-TB-28V/V Anti-Dither Module
The BEI Sensors EM-DR1-DB4-5-TB-28V/V is a robust industrial anti-dither module designed to eliminate signal instability from rotary or linear encoders caused by mechanical vibration. By filtering out this “dither,” the module provides a clean, stable square wave output to the controller, ensuring accurate and reliable position feedback in demanding motion control systems. Featuring a versatile 5-28 VDC supply voltage and a convenient DIN rail mounting design (35 x 7.5mm), this module seamlessly integrates into standard control cabinets to enhance system precision and prevent false counts.
