Industrial position sensing

The Autonics ENC-1-2-N-24 is an incremental rotary encoder designed for motion-control systems that need reliable position feedback. It delivers 100 pulses per revolution through NPN open-collector outputs suited to 12-24 VDC logic.

Thermals and power

The encoder draws power from a 12-24 VDC supply with a maximum 5 % ripple and operates up to a 180 kHz response frequency. Mechanical speed is rated to 5000 rpm, so heat and acoustic noise remain negligible in typical continuous operation.

Build integration

An axial cable provides a direct connection to the controller, while the 250 mm measuring wheel and 4:1 gear ratio translate linear travel into encoder pulses. The NPN output stage requires a pull-up resistor at the receiving input, and the 12-24 VDC range matches common industrial power rails.

Questions about this item

How do I wire the axial cable for the 12-24VDC NPN open collector output?

Connect the red wire to 12-24VDC, black to ground, and the A and B phase wires to your controller inputs; the step often missed is adding pull-up resistors on A and B because the NPN outputs only sink current.

What maintenance does the measuring wheel need after extended use?

The 250mm wheel and 4:1 gear set should be checked periodically for debris and bearing play; clean the wheel surface and verify the gear mesh stays smooth to keep the 100 pulse count accurate.

At what speed does the 180kHz response frequency limit the encoder?

The 180kHz maximum response frequency is reached at 5000rpm; beyond that speed the A and B phase signals can no longer switch cleanly, so the 5000rpm mechanical limit is the practical ceiling.
