Chemical Resistance
 Applicable Model
Chemicals that affect Tags are shown below.
Polybutylene terephthalate (PBT) resin is used for case material and epoxy resin for filling material. Refer to
the following lists and do not use chemicals that affect PBT and epoxy resins.
Tags cannot be used in applications with explosion-proof specifications.
 Chemicals That Cause Deformations, Cracks, Etc.
 Chemicals That May Cause Discoloration, Swelling, Etc.
 Chemicals That Do Not Affect PPS Resin or Epoxy Resin
Note: The above results are from tests conducted at room temperature (23°C). Even if the chemicals
do not affect the PPS or epoxy resins at room temperature, they may affect the resins at higher or lower
temperatures. Check the chemicals carefully in advance.
