Rotary Position Encoder, absolute analog 4-20mA current output, 6.35mm shaft, short  -  RPE3-635-PA

Please note: RPE3-635-PA is now at EOL due to discontinuation of certain parts. The replacement device is RPE4-635-S which has better stability, higher resolution and accuracy. RPE4-635-S is now available.

Other RPE3 models are available in shaft sizes 6.35mm and 8mm.
