**Hour meters / timers, electromechanical** 

## **Micro timers** 

## **Many different installation options (DC)** 

## **HK07 / AHK07** 

**The micro timers of the HK07 and AHK07 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.** 

## **Characteristics** 

- 7-digit micro hour meter. 

- High shock and impact resistance. 

- Low power consumption; suitable for battery operation. 

## **Benefits** 

   - Wide voltage range 4.5 ... 35 V DC. 

   - Count retention in case of power failure. 

   - Long service life. 

- Small dimensions – magnified large figures. 

- Panel-mount counter with integrated spring clip. 

- PCB-mount counter. 

- Machine-solderable and wash-proof. 

## **Applications** 

General time measurement, maintenance intervals for measuring instruments (respiration units, oxygen, dialysis), small appliances, 

•   Protection IP65. UV lamps, display panels in vehicles.
