Hall-Effect Single-Turn Rotary Encoder with Analog Output
Series ENA22K
Specications are subject to change without notice
No mechanical wearing
Analog output (voltage, current, redundant)
Versatile programming ex works
Potted electronics
Life expectancy > 25 x 10

shaft revolutions
The Hall effect Kit-Encoder Series ENA22K has an endless
mechanical life expectancy because there is no bearing nor
wear. A separate magnet is enclosed. There are push on
magnet holders as an accessory available.
Due to the easy connection of the at ribbon cable,
e.g. using IDC, the cost of soldering can be reduced as well.

Function description PWM signal output ENA22K
The rotary encoder ENA22K supplies as output signal 244Hz constant carrier frequency with
dened high low ratio. The duty cycle (ratio between high and low value) changes in depend-
ency of the rotation angle. The duty cycle lies between 10% and 90%.
If the option CW is chosen the duty cycle increases clockwise. If option CCW was chosen the
duty cycle decreases clockwise. Normally for PWM signals no further processing - for example
an external analog/digital converter - is needed, because many micro controllers are equipped
with a PWM input.
