Samkoon HMI to PLC Communication Cable (2.5m)
Product Overview
The Samkoon HMI to PLC Communication Cable is a specialized 2.5-meter communication cable designed to connect Samkoon HMIs to Samkoon PLCs equipped with a 4-pin Mini-DIN serial port. This cable provides a stable, high-speed RS-232 data link, ensuring error-free screen updates and rapid command execution in industrial automation environments.
Key Features
- Precision Connectors: Features a standard DB9 Female for the HMI side and a 4-Pin Mini-DIN Male for the PLC side.
- Extended 2.5-Meter Length: Offers 1 meter of additional reach over standard cables, allowing for cleaner cable management in tall or deep control cabinets.
- Industrial Shielding: Built with an aluminum-platinum foil shield and a high-density tinned copper braid to eliminate electromagnetic interference (EMI).
- Gold-Plated Pins: Ensures low contact resistance and prevents oxidation, which is critical for low-voltage RS-232 signals.
- Rugged Construction: The 4-pin Mini-DIN end is reinforced with a molded PVC strain relief to prevent internal wire breakage from frequent plugging or vibration.
