PSC Series ERN1387 Compatible 2048 Line Taper Hollow Shaft Incremental Rotary Encoder

Product name : PSC Series ERN1387 Compatible 2048 Line Taper Hollow Shaft Incremental Rotary Encoder
Product Categories : Through Hollow Shaft Rotary Encoder
Product Description： PSC series ERN1387 compatible encoder is a direct drop-in replacement for original Heidenhain ERN1387-2048 incremental rotary encoder, widely used on AC servo motors and elevator traction machines. It adopts 9.25mm standard 1:10 taper hollow shaft with integral bearing design, outputs 2048-period 1Vpp sine/cosine ABZ incremental signals for high subdivision precision, powered by DC5V ±5V. Equipped with flexible stator coupling anti-rotation bracket, max rotation speed up to 15000RPM, system accuracy ±20 arc seconds, IP40 standard protection grade. Same mounting size, pin definition and signal waveform as original ERN1387, no modification required during replacement, stable anti-vibration performance for CNC spindles, lifting equipment and automation closed-loop control.
