Model Number

FSS58

Features

• Industrial standard

housing Ø58 mm

• 13 Bit singleturn

• Output code: gray and binary

• Short-circuit proof push-pull out-

put

• Inputs for selecting counting di-

rection, LATCH, and PRESET

• Code change frequency up to 400

kHz

• Recessed hollow shaft

Description

The emphasis for this series is on rapid data trans-

fer. Position data are read directly out of the Gray

code disc. The high code switching frequency of

400 kHz is achieved by consciously avoiding the

use of a microcontroller.

The FSS58 singleturn absolute encoder is equip-

ped with a recessed hollow shaft. The encoder

housing has a diameter of 58 mm. The recessed

hollow shaft is available with diameters of 10 mm,

12 mm and 15 mm.

This version in particular represents a simple and

cost-effective mounting solution. The shaft hub

connection is already integrated into the rotary en-

coder. The rotary encoder is held in place by a

torque rest.
