Epoxy-coated N35 pot magnet for added corrosion resistance in humid and outdoor applications. 25 mm diameter; listed pull force 45.4 lb. Coating integrity should be validated for immersion or aggressive environments.
SKU 9170 is a 25 mm N35 epoxy-coated pot magnet, Model A25, with a listed 45.4 lb pull force. Its steel cup concentrates the magnetic circuit at the working face, while the epoxy coating adds a corrosion barrier for engineers, OEMs, and procurement teams evaluating compact mounting magnets for humid, outdoor, fixture, and equipment applications.

The epoxy coating provides an added corrosion barrier, but coating integrity should still be protected from chips, abrasion, and impact. For immersion or aggressive chemical exposure, validate the complete assembly and coating system for the specific service environment.
The listed pull force is a reference value under favorable direct-contact conditions and can be reduced by air gap, paint, thin steel, surface roughness, curvature, temperature, and side loading. Use the Magnet Pull Force Calculator for preliminary screening and browse pot and mounting magnets for related styles.
