Frequently Asked Questions

Q: What does "S-Coded" mean on an M12 connector?

A: S-coding is a keying system used on M12 circular connectors specifically designated for AC/DC motor power supply applications. The unique S-shaped key prevents accidental mating with D-coded (DeviceNet), A-coded (sensor/signal), or other M12 variants, ensuring safe and correct connections in multi-connector industrial panels.

Q: Is this M12 S-Coded Plug Connector waterproof?

A: Yes. This connector is built to IP67 waterproof standards, meaning it can withstand water jets and temporary immersion, making it suitable for wet, humid, or wash-down industrial environments where moisture resistance is essential.

Q: What material is the M12 S-Coded Connector housing made from?

A: The housing is constructed from PA66 (Polyamide 66), a high-strength engineering thermoplastic known for its excellent heat resistance, chemical resistance, and mechanical durability — ideal for demanding industrial applications.

Q: What is the mounting thread type and tightening torque for this connector?

A: This connector uses an M16 x 1.5 front-panel mounting thread with a recommended tightening torque of 4 Nm for a secure, vibration-resistant installation on control panels or enclosures.

Q: Is this connector halogen-free?

A: Yes, this M12 S-coded connector is halogen-free, making it compliant with environmental and fire-safety standards commonly required in industrial automation, robotics, and European CE-compliant machinery.
