Product Frequently Asked Questions (FAQ)

Q1: What is the difference between A-code and B-code M8 connectors?
A1: A-coded M8 connectors are standardized for 3-pin or 4-pin configurations used in sensors, data, and power. B-coded M8 connectors are specifically for 4-pin PROFIBUS networks and feature a different keying position to prevent mating with A-coded sockets. Our 4-Pin A-Coded Connector is not compatible with B-coded systems.

Q2: Can this connector be used for power transmission?
A2: While it can carry power, the M8 4-pin A-coded connector is primarily optimized for data and signal transmission, such as in Ethernet/IP applications. For dedicated power applications, it is crucial to check the voltage and current ratings against your requirements to avoid overheating.

Q3: What is the significance of the IP67 rating?
A3: The IP67 rating means the connector is "Ingress Protection" level 6 (completely dust-tight) and level 7 (protected against immersion in water between 15cm and 1 meter for up to 30 minutes). This makes it suitable for environments with high dust, humidity, or occasional water exposure, like factory wash-down areas.

Q4: What types of cable are best suited for this connector?
A4: We recommend using PUR (Polyurethane) jacketed cables for the best performance in harsh conditions. PUR offers superior resistance to oil, chemicals, abrasion, and hydrolysis. PVC cables are a cost-effective alternative for less demanding, general-purpose indoor applications.

Q5: Is this a plug or a socket?
A5: This specific product is a Male connector, meaning it has the pins. It is designed to mate with a Female M8 connector, which has the sockets.
