OPTO-TOUCH Field Covers (see drawing, below) are designed to
prevent inadvertent activation of OPTO-TOUCHs due to objects
(loose clothing, debris, etc.) which might accidentally block their
sensing beam.
Field covers are constructed of rugged polycarbonate-PET polyester
blend, which is capable of absorbing high impacts (even at low
temperatures). This material is highly resistant to abrasion and to
damage by most chemicals.
Every OPTO-TOUCH is supplied with a black field cover, as standard.
Field covers are available separately in four colors, which can be used
to differentiate touch button functions when several touch buttons are
in use:

Yellow model OTC-1-YW, p/n 30978
Green model OTC-1-GN, p/n 30979
