FAQ
Why use a 0.5-meter cable?
It offers cleaner routing in compact spaces and provides lower resistance for improved signal quality.
What benefit does the 2-inch housing provide?
It improves stability during high-vibration operation and supports deeper installation.
Can this model enter explosive areas?
Yes, the CN variant meets CSA, ATEX, and IECEx requirements for hazardous locations.
How does the armored design help?
It protects the cable from mechanical stress, especially in tight industrial pathways.
Why does the short cable affect resistance?
Shorter cable length reduces total loop resistance, producing the measured 7.45-ohm value.
