ASS58/ASM58 Series
SSI Interface
• Industrial standard 58 mm diameter housing
• Single or multi-turn
• IP65
• 10 or 12 mm diameter shaft
Pepperl+Fuchs’ ASS58/ASM58 series absolute encoders feature
recessed hollow shafts and communicate via SSI (synchronous serial
interface). The encoder is mounted directly to the shaft using set
screws. The torque rest is used to prevent the encoder from rotating.
Available in either single-turn with 16-bit resolution, or multi-turn with
30-bit resolution versions. These encoders are rated IP65 and feature
a rugged aluminum housing.
