The ever increasing operating speeds of today demand an encoder that is durable and resistent to vibration, shaft run-out and axial movement. Our encoders feature a robust dual-bearing design and an overhang load capability that is 3x the industry average to compensate for these common issues and to prevent any unnecessary encoder related downtimes.

All EMP Encoders carry a one-year warranty and are 100% plant tested. Our dual-bearing encoders are shock resistant and available in the following sizes:
