Digital Counter

H7BR

Easy-to-Use Multifunction Counters
with Backlit LCD Display

■

Compact, 72 mm (2.83 in) square
— includes single and double preset,
and +/– range

■

Both contact and transistor outputs
available

■

Prescale function displays in units
of actual physical parameters
(length, volume, etc.)

■

H7BR-C provides large/small
discrimination mode — ideal for
positioning and production control

■

Batch counter in H7BR-B lets you
count in dozens, hundreds, or any
count preset

■

On-line change of set value possible
