Product Overview

The Omron E6CP-AG5C 256P-R is a general-purpose absolute rotary encoder from the E6CP-A family, manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.

The encoder delivers 256 divisions per revolution (8-bit) in gray code on an open-collector NPN output. Supply is 12-24 VDC (12 VDC -10% to 24 VDC +15%, ripple p-p 5% max) at 70 mA max. Maximum response frequency is 5 kHz and accuracy is +/-1 degree. Rotation is CW from the shaft, with negative logic (H = 0, L = 1).

The 50 mm plastic body carries a 6 mm solid shaft and a 2 m pre-wired cable. Shaft load is radial 10 N / axial 5 N and max rotation 5,000 r/min. For an incremental sibling in the same 50 mm body, use the E6C2-CWZ5B 500PR 2M. For 5-12 VDC supply use the E6CP-AG3C sibling.

Key Features

  • E6CP-series absolute rotary encoder, 50 mm body, 6 mm solid shaft, 2 m pre-wired cable
  • 256 divisions per revolution, 8-bit gray code output, open-collector NPN, 12-24 VDC supply
  • 5 kHz max response frequency, +/-1 degree accuracy, negative logic, CW rotation = code up
  • Starting torque 1 mN-m max, IP50, 5,000 r/min max speed, plastic body for low weight
  • SKU: E6CP-AG5C 256P-R
  • Series: Omron E6CP-A series general-purpose absolute rotary encoder
  • Voltage: 12 VDC

Best-Fit Applications

  • Turntable position feedback on a labeling machine where the gray code absolute position lets the host PLC resume indexing after a power cycle without re-homing
  • Damper / valve position indicator on an HVAC fan coil where 256 divisions over 360 degrees is enough resolution for the actuator's set-point profile
  • Spare replacement on a long-running packaging line where the old E6CP-AG5C 256P/R has been superseded and a like-for-like encoder is needed in the same mounting

Buying Checklist

  • Pick the E6CP-AG5C 256P-R for an absolute gray-code encoder at 12-24 VDC supply with 256 divisions on a 50 mm body.
  • Pick the E6CP-AG3C instead when the host controller or sensor supply is 5-12 VDC only.
  • Pick the E6C2-CWZ6C instead when an incremental A/B/Z pulse train is enough and the panel can re-home on power-up.

FAQ for E6CP-AG5C 256P-R

What is the Omron E6CP-AG5C 256P-R used for?
It is a 50 mm absolute rotary encoder for turntable, valve, and door position feedback. The 8-bit gray code output lets the host PLC know the shaft position the moment power returns, with no re-homing.
E6CP-AG5C vs E6CP-AG3C - what is the difference?
The E6CP-AG5C accepts 12-24 VDC supply. The E6CP-AG3C accepts 5-12 VDC supply. Resolution (256 divisions), output code (gray code), and mechanical body are identical between the two.
Does the E6CP-AG5C 256P-R output incremental pulses?
No. The E6CP-AG5C outputs absolute gray code, 8 bits of position per revolution. For incremental A/B/Z pulses pick the E6C2-CWZ6C sibling in the same 50 mm body.
How is the E6CP-AG5C 256P-R wired?
Six wires in the 2 m PVC pigtail cable: red +V supply, black 0 V common, brown output bit 20 (MSB), and three more output wires for the remaining bits, plus an orange enable / shield line. See the datasheet for the exact color map and the E69-C06B coupling accessory.
What is the starting torque of the E6CP-AG5C 256P-R?
1 mN-m max, with moment of inertia 1 x 10^-7 kg-m^2. Shaft load is radial 10 N / axial 5 N. These are the same mechanical limits on the E6CP-AG5C-C sibling and the older E6CP-AG3C.
