Product Description Ordering Key
24 x 48 digital counters
24 x 48 mm up to 2 inputs
up-down counters for flush
mounting. NPN, PNP or volt-
age inputs allow connection
to any type of sensors or
open collector output. The
front key, which can be
locked, allows fast and easy
counting reset.
•8-digit LCD display
