SAH99 Heavy-Duty Incremental Encoder

SAH99Heavy Duty Incremental Encoders
With lightning, over-voltage, over-current, surge impact protection
The housing is protected against dust and liquids by a rugged enclosure with protection class IP67. Versions for hazardous environments are ATEX certified
Up to 10,000 P/R pulses per revolution
Dual output module available with double scanning sensor and two electrically isolated electronic circuits
This dual output signal can be used for two separate systems with different functions or for obtaining redundant signals.
Hollow shafts fixed with axial screws. Shaft sizes: Ø12 mm, Ø16 mm and Ø17 mm tapered shafts. Insulated PEEK bushings to protect the bearings from shaft currents.
Torque brackets are available in a variety of orientations to hold the torque arm. Separate rear cover for connecting cable wires to screw type terminals Ample space for easy access during connection.
Handling operations are performed when the cable is M23 Connector or pre-assembled cable (with or without connector)
