Incremental rotary encoder 100P/R

The Autonics E40S6-100-6-L-5 is an incremental rotary encoder that delivers 100 pulses per revolution with a maximum response frequency of 300kHz. It operates on a 5VDC ±5% power supply and provides line driver control output through a radial cable connection. The unit has a 6mm shaft diameter and is rated for up to 5000rpm. Its IP50 protection structure guards against dust ingress.

Suited for precision motion feedback

This encoder suits applications that require accurate position or speed feedback at moderate resolutions, such as conveyor positioning, packaging machinery or small CNC axes. The 100P/R resolution and 300kHz response frequency limit its use in ultra-high-precision or very high-speed servo loops. Buyers needing finer resolution or higher pulse rates should consider other models.

Resolution decides fit

The single specification that determines whether this encoder fits the application is its 100P/R resolution. This value sets the smallest detectable angular step and directly defines the positional granularity available to the controller. If the system demands a different pulse count per revolution, this part will not match the requirement.

Questions about this item

What does the 300kHz maximum response frequency limit for the Autonics E40S6-100-6-L-5 encoder?

The 300kHz cap restricts the maximum pulse output rate; at 100P/R resolution it corresponds to 5000rpm, so shaft speed must stay at or below that value to avoid lost counts.

What shaft diameter does the E40S6-100-6-L-5 require for mounting?

The encoder has a Ø6mm shaft outer diameter, so the mating coupling or gear bore must match 6mm for a secure fit.

How is the radial cable connected and what wiring mistake is common?

The 5VDC ±5% supply and line-driver outputs exit radially; a frequent error is reversing the A/B phase wires, which inverts the direction signal.
