Defining the CAB-PWR-C7-CHE-A=

The ​​CAB-PWR-C7-CHE-A=​​ is a Cisco-certified power cable engineered for environments exposed to ​​chemicals, oils, or high humidity​​. Featuring a ​​C7 connector​​ (IEC 60320 standard), it powers low-wattage Cisco devices like compact switches, IP phones, or IoT gateways in industrial or laboratory settings. Its specialized construction resists corrosion and degradation caused by aggressive substances.

Technical Specifications

• ​​Connector Type​​: C7 (non-polarized, two-prong) to C8 receptacle, rated for ​​250V AC, 2.5A​​ (625W max).
• ​​Cable Length​​: 1.8 meters (5.9 feet), with ​​20 AWG stranded copper conductors​​ for flexibility.
• ​​Jacket Material​​: ​​Chemical-resistant PVC​​ compliant with UL 94V-2 flame-retardant standards.
• ​​Certifications​​: UL, CE, RoHS, and resistant to IP55-rated dust/moisture ingress.

​​Why C7 connectors?​​ Their compact design suits space-constrained devices like Cisco IP Phones 6800/7800 series or small switches (e.g., CBS110).

Key Applications

1. ​​Laboratory Networks​​: Powers Cisco IoT sensors or switches near chemical fume hoods or wet benches.
2. ​​Industrial IoT Deployments​​: Connects Catalyst IE1000 switches in food processing or pharmaceutical plants.
3. ​​Outdoor Kiosks​​: Withstands cleaning agents and humidity in self-service terminals or digital signage.

Addressing User Concerns

​​Q: Is this cable compatible with non-Cisco devices?​​
Yes, but ensure the device’s power inlet matches the C8 connector. Avoid using with high-power equipment exceeding 2.5A.

​​Q: Can it withstand prolonged exposure to solvents like acetone?​​
Yes. The PVC jacket resists ​​common industrial solvents​​, but prolonged immersion in aggressive chemicals (e.g., benzene) is not recommended.

​​Q: How does it differ from standard C7 cables?​​
Cisco’s ​​reinforced jacket​​ and ​​corrosion-proof contacts​​ prevent brittleness and oxidation in humid or acidic environments.

​​Q: Does it support PoE (Power over Ethernet)?​​
No. This is a standalone AC power cable and does not transmit data or PoE.

Sourcing the CAB-PWR-C7-CHE-A=

For chemical-resistant reliability, the “CAB-PWR-C7-CHE-A=” is available here, alongside Cisco’s industrial-grade power solutions.

Field Experience

During a wastewater treatment plant upgrade, standard power cables failed within months due to hydrogen sulfide exposure. Replacing them with the CAB-PWR-C7-CHE-A= eliminated corrosion-related outages, despite its higher initial cost. For facilities handling volatile substances, this cable’s durability justifies the investment—though regular inspections are still advised. Always verify voltage compatibility, as its 250V rating may not suit all regional power grids.
