SICK STEGMANN SRS50-HFA0-K01 Encoder Motor Feedback Connector

SRS50-HFA0-K01 is an 8-pin, male encoder-motor feedback connector from SICK STEGMANN designed to terminate the SRS50/SRM50 motor feedback system and provide encoder power and signal channels in a compact plug‑in interface. It operates from 7–12 V DC and draws about 80 mA, making it suitable for inline power and data termination in SRS50/SRM50 installations. The pinout uses eight wires: 1 Us (red) for encoder supply 7–12 V; 2 GND (blue) ground; 3 REFSIN (brown) process data channel; 4 REFCOS (black) process data channel; 5 Data+ (grey) RS-485 parameter channel; 6 Data- (green) RS-485 parameter channel; 7 +SIN (white) process data channel; 8 +COS (pink) process data channel. The shield screen lead, about 200 mm, must be connected to the encoder housing to maintain proper shielding. The part is identified by the number SRS50-HFA0-K01 and carries the factory code 1034222; typical weight is around 0.11 kg, and the item is listed as discontinued by the manufacturer. This connector is commonly used with SRS50 and SRM50 motor feedback systems to deliver power and multi‑channel feedback signals in a single, ready‑to‑install assembly for industrial motion control.
