Description
The type 07-662.-..../.... potentiometer consists
of a metal Ex d enclosure, into which an inser-
tion potentiometer is fitted.
The metal Ex d enclosures are tailored to the
dimensions of the resistors and will be pro-
duced in different sizes from Ø 30 to 60 mm
(1.18 to 2.36 in).
The potentiometer can be fastened and secured
against twisting in a number of ways. Two nuts
are included in each consignment. Optionally
BARTEC provides either threaded holes in the
front panel of the enclosure or an antirotation
pin.
Accessories, such as rotary and pointer knobs,
scales, digital drives for 10 turns potentiometer,
and slip clutches could be delivered.
