Autonics EP50S8 N Series Product Manual
Cautions during Installation
• Install the unit correctly with the usage environment, location, and the designated
specifications.
• Do not load overweight on the shaft.
• Do not put strong impact when insert a coupling into shaft.
Failure to follow this instruction may result in product damage.
• When fixing the product or coupling with a wrench, tighten under 0.15 N m.
• If the coupling error (parallel misalignment, angular misalignment) between the shaft
increases while installation, the life cycle of the coupling and the encoder can be
shorten.
• Do not apply tensile strength over 30 N to the cable.
Ordering Information
This is only for reference, the actual prodcut does not support all combinations.
For selecting the specified model, follow the Autonics website.

Product Components
• Product
• Instruction manual
Connections
• Unused wires must be insulated.
• The metal case and shield cable of encoders must be grounded (F.G.).
• F.G. (Frame Ground) must be grounded separately.
• Since exclusive driver IC is used for output circuit, be aware of short circuits when
wiring each output wires.
• N·C: not connected

Inner Circuit
• The output circuit is identical for each output bit.
• Be aware of circuit break in case of overload or short beyond the specifications.
■ PNP open collector output
Output Waveform
• Following waveform is based on the positive logic.
(In case of negative logic, the waveform is opposite to corresponding waveform.)
