Type SCH94FO Description Description 

• Hollow Shaft Fiber Optic Encoder - Ø 94 mm 

• Dual Output Option (Digital & Fiber Optic) 

• Fiber Optic Transmission up to 2,000 meters (~ 1.25 miles) 

No Degradation of Encoder Signal from Electrical Disturbances 

• High Encoder Frequency and Low Transmission Delay 

• Added Safety by use of two Redundant Fibers 

• Built-in Transient Suppression Module 

The SCANCON SCH94FO is a heavy-duty incremental encoder offering Fiber Optic output. The SCH94FO incorporates the rugged design features of SCANCON’s industry standard SCH94 hollow shaft encoder with the high transmission distance and noise resistant qualities of Fiber Optics. The result is the industry’s first rugged and reliable, dualoutput Fiber Optic encoder. Specifically designed for the Wind Power Industry, the SCH94FO-SA can also be used in Industrial applications which require noise-free signal transmission over distances up to 2000 meters. Utilizing both Fiber Optic cable and a built-in Transient Suppression Module (TSM), the encoder protects against signal disruption by electrical disturbances often encountered during operation of industrial equipment. In addition, the encoder is protected against lightning strikes.

The SCH94FO-SA encoder is designed to operate with both a Digital output and a Fiber Optic output. The customer may also choose to use only the Fiber Optic output. The encoder offers Infrared Light transmission. The Infrared Light option allows for a much longer transmission distance (up to 2,000 meters). The SCH94FO-SA encoder is ideal for those applications requiring safe signal transmission over long distances.
