Features
• Industrial standard
housing Ø58 mm
• 13 Bit singleturn

• Short-circuit proof push-pull output
• Inputs for selecting counting direction, LATCH, and PRESET
• Code change frequency up to 400
kHz
• Recessed hollow shaft
Description
The emphasis for this series is on rapid data transfer. 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 equipped 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 encoder. The rotary encoder is held in place by a
torque rest.

Input for selection of counting direction (V/R)
The counting direction for the absolute value rotary encoder as seen looking on the shaft is defined as right rotating (cw) rising or descending. The counting
direction can be reversed with the V/R input. If the input is not used, the counting direction is defined as rising (standard), the level is at "1". Pulse duration
T > 10 ms.
Input level: "1" or unused = rising code value with direction of rotation cw.
Input level: "0" = descending code value for direction of rotation cw.
Input for temporary storage (LATCH)
With LATCH input "active", the position data on the parallel interface are "frozen". This makes it possible to accept position data without errors (especially
for binary position data), since any change in the data during the read procedure is prevented. If this input is unused, its value is "0". Pulse duration T > 100
µs.
Input level: "1" = position data saved and stable at the output.
Input level: "0" or unused = position data free running at the output.
Input zero setting (PRESET)
By means of the PRESET input, the absolute value rotary encoder can be adjusted electronically to position value 0. Pulse duration T > 10 ms.
Input level: "0" or unused = inactive.
Input level: "1" = Data output word is set to 0.
