We supply Encoders with Incremental signals - ~11 µAPP sinusoidal signals. We have Heidenhain and other Equivalent Encoders available.
The ~11 µAPP are in stock at Dubai available for despatch
HEIDENHAIN encoders with ~11 µAPP
interface provide current signals. They are intended for connection to ND position display units or EXE pulse-shaping electronics from HEIDENHAIN.
The sinusoidal incremental signals I1 and I2 are phase-shifted by 90° elec. and have signal levels of typically 11 µAPP.
The illustrated sequence of output signals—with I2 lagging I1—applies to the direction of motion shown in the dimension drawing, and for retracting plungers of length gauges.
The reference mark signal I0 has a usable component G of approx. 5.5 µA.
The data on signal amplitude apply when the supply voltage given in the Specifications is connected at the encoder. They refer to a differential measurement between the associated outputs. The signal
amplitude decreases with increasing frequency. The cutoff frequency indicates
the scanning frequency up to which a certain percentage of the original signal
amplitude is maintained:
• –3 dB cutoff frequency:
70% of the signal amplitude
• –6 dB-cutoff frequency:
50% of the signal amplitude
The output signals of the 11 µAPP interface are usually interpolated in the subsequent
electronics—ND position displays or EXE pulse-shaping electronics from HEIDENHAIN—in
order to attain sufficiently high resolutions.
