FAQ

Question
The catalog page for the CFS2 level switches states, “Optional cables available include those with drinking water suitability.” Which cable should I specify for use in a drinking water application?
Answer
Our cables that are compatible with drinking water must be purchased in quantities of 1000pcs. The cables we carry in stock that have a minimum order quantity of 1 pc are not drinking water approved.
