Rotary encoder for position feedback
The Autonics E40S6-256-3-N-24 is an incremental rotary encoder with NPN open-collector output. It delivers 256 pulses per revolution and operates on a 12-24VDC supply. The Ø6 mm shaft supports speeds up to 5000 rpm with a starting torque of 40 gf·cm. Protection is rated IP50.
Suits PLC inputs and simple motion control
Engineers integrating position feedback into PLCs, conveyor drives or packaging machines will find the 300 kHz response frequency and radial cable convenient. The unit is not for applications that require absolute position data, higher resolution than 256 P/R, or environmental sealing beyond IP50.
256 pulses per revolution decides fit
The single specification that determines compatibility is the 256 P/R resolution. If the control system expects a different pulse count per turn, this encoder will not match the required scaling.

Questions about this item
What shaft diameter does the 6 mm encoder shaft fit?
The encoder has a Ø6 mm shaft outer diameter, so it fits a 6 mm bore or coupling.
How do I wire the radial cable without crossing the A and B channels?
Follow the cable colour code for NPN open-collector outputs: typically brown for VCC, blue for GND, black for A-phase, white for B-phase, and orange for Z-phase.
How often should I check the starting torque spec of 40 gf·cm?
Verify the starting torque remains below 40 gf·cm (0.00392 N·m) during routine maintenance; if it rises, inspect bearings and shaft alignment.
