Key Technical Characteristics

• Premium Insulation Technology: The cable is shielded with a high-performance polyurethane (PUR) conductive coating. This material provides a robust barrier against industrial contaminants, moisture, and chemical exposure while enhancing the cable’s overall dielectric properties.

• Broad Connectivity Interface: Engineered for versatility, the RH916DB supports dual-interface standards, allowing for secure integration with both BNC-type and M12 industrial connectors. This flexibility simplifies spare part management across various system architectures.

• Extreme Thermal Resilience: This cable assembly is certified to maintain its mechanical and electrical specifications across a wide temperature spectrum (-40°C to +85°C). It is ideally suited for installations in both sub-zero outdoor enclosures and high-heat production environments.

• High Tensile Strength: The assembly is designed with high pull strength to withstand the physical rigors of installation and long-term use in high-vibration settings. This prevents intermittent signal loss caused by mechanical tension on the termination points.

• Optimized Signal Integrity: By utilizing multi-strand copper cores, the RH916DB minimizes signal attenuation. This ensures that the data processed by the 200 Series modules remains accurate and free from the distortion typically caused by low-quality cabling.

• Sustainable Compliance: Fully compliant with RoHS standards, the cable is manufactured without hazardous substances, ensuring environmental safety and alignment with global industrial regulations.
