Appropriate pulse generators are required in order to achieve accurate count results. In this connection, it should be ensured that these operate as far as possible without bounce; this is particularly important for counters with high pulse rate.
Cam operated spring contacts, limit switches and microswitches are suitable for count speeds up to approx. 10 or 25/cps, small relay contacts up to approx. 40 cps, higher count speed up to 60/cps. can be achieved with reed switches, exact matching of spark quenching being necessary to avoid premature sticking of contact reeds. Even higher speeds can be obtained by using photoelectric or inductive sensors. Our pulse generators which are manufactured in a robust and solid style are suitable for count speeds up to maximum of 60/cps.
