The connection terminals of the small-format Type 633 DC match standard configuration patterns. The small dimensions and low power consumption make this the ideal time counter for installation on PCBs. Types 0 can be machine-soldered and can, if necessary, be washed with no problems. The construction is particularly impact-resistant.
