Hour meters / timers, electromechanical Micro timers Many different installation options (DC) HK 07 / AHK 07 The micro timers of the HK 07 and AHK 07 families offer a particularly large number of variants and can be used in many different applications thanks to their wide voltage range from 4.5 to 35 V DC. Available as panel, base and PCB mount versions, they can be used in many different fields of application. Thanks to their encapsulated housing, these non-resettable counters are extremely tamper-proof. RoHS Characteristics Benefits 7-digit micro hour meter Wide voltage range 4.5 ... 35 V DC High shock and impact resistance Count retention in case of power failure Low power consumption suitable for battery operation Long service life Small dimensions magnified large figures Panel-mount counter with integrated spring clip Applications PCB-mount counter General time measurement, maintenance intervals for measuring Machine-solderable and wash-proof instruments (respiration units, oxygen, dialysis), small appliances, Protection IP65 UV lamps, display panels in vehicles Type series Fig. Mounting options Display Protection El. connection Housing Height of fig.
