Opscom M8 series follows the IEC 61076-2-104 international standard .
3/4 pin adopt universal definition for sensor field (e.g. 4 pin: 1=V+, 2=S+, 3=S-, 4=V-).
5/8 pin can be customized according to customer needs .
M8 connectors with same specification & pin definition can be intermateable across brands.
Industrial scenario recommendation: Prioritize the same brand full set of products to avoid poor contact caused by contact piece tolerance.
4 Pin Universal Definition Reference: 1 = Power +, 2 = Signal +, 3 = Signal -, 4 = Power -
Technical Note: The universal pin definition of 3/4 pin M8 connectors is the basis for cross-brand compatibility in the sensor industry; for customized 5/8 pin products, it is necessary to confirm the pin definition drawing with the supplier in advance to avoid wrong connection; the same brand products have unified contact piece tolerance standards, which can effectively ensure the stability of long-term plugging and contact performance.
