| Core Count | Typical Application | Recommended Coding | Opscom Adaptation |
|---|---|---|---|
| 3 Core | DC Power Supply (e.g. 24V Sensor) | A Coding | Straight/Elbow Cable End / Panel End |
| 4 Core | Digital Signal (e.g. PNP/NPN Sensor) | A Coding | Shielded/Unshielded Harness |
| 5 Core | Analog Signal / IO-Link | A/B Coding | Quick Wiring Type |
| 8 Core | Industrial Ethernet (e.g. PROFINET) | D Coding | Shielded High Protection Model |
A Coding
is dedicated to sensors/actuators,
D Coding
is adapted to industrial Ethernet.
The physical foolproof structure of different codings avoids wrong insertion, preventing signal short circuit and equipment damage caused by mismatched connection.
Technical Note: When selecting M8 connectors for industrial Ethernet scenarios (8-core D coding), it is recommended to prioritize shielded high-protection models to reduce electromagnetic interference and ensure stable data transmission; for IO-Link communication (5-core), confirm the coding type (A/B) with the equipment supplier in advance to ensure protocol compatibility; the coding foolproof design is a mandatory standard for industrial M8 connectors, and non-standard products should be avoided to prevent on-site application risks.
