What Are the Pinout Configurations for an M8 Circular 6Pin Connector Female
2026-06-09
When designing compact automation systems, understanding the pinout of an M8 Circular 6Pin Connector Female is critical. At Signalorigin, we frequently help engineers decode these configurations to prevent wiring errors. Typically, this connector follows IEC 61076-2-104 standards, with pins assigned for power, signal, and shielding.
Standard Pinout Table (View from soldering side)
| Pin Number | Common Assignment | Color Code (IEC) |
|---|---|---|
| 1 | DC+ (24V) | Brown |
| 2 | Signal 1 | White |
| 3 | DC- (0V) | Blue |
| 4 | Signal 2 | Black |
| 5 | Signal 3 / SGND | Grey |
| 6 | Shield / PE | Orange |
Note: Always verify with your device datasheet. Signalorigin provides custom pin mapping for OEMs.
Visual Wiring List

M8 Circular 6Pin Connector Female – FAQ
Q1: Can I use an M8 Circular 6Pin Connector Female for both analog and digital signals?
Yes. The M8 Circular 6Pin Connector Female supports 0-10V analog, 4-20mA loops, and digital protocols like IO-Link. At Signalorigin, we recommend separating analog lines (pins 2,4) from power (pin1) to avoid crosstalk. Shielding on pin6 is mandatory for analog accuracy above 10kHz.
Q2: What happens if I reverse the power pins on an M8 Circular 6Pin Connector Female?
Reversing pins 1 and 3 can immediately damage downstream electronics. Most M8 Circular 6Pin Connector Female models lack reverse polarity protection. Signalorigin offers variants with built-in diode protection. Always label wire colors during assembly.
Q3: How do I verify the pinout without a datasheet?
Use a multimeter in continuity mode. Touch one probe to pin1 of the M8 Circular 6Pin Connector Female and the other to each wire end. For Signalorigin certified connectors, the brown wire always corresponds to pin1. If readings are unstable, the internal PCB may be faulty.
