00335990 is a digital rotary encoder (read head) for the DP axis of the ASM SIPLACE RV12 (C&P12/DLM) placement head; it serves as a high-precision core sensing component.
Core Function and Positioning
Installed at the front of the RV12 placement head, this read head detects the rotational position and speed of the DP axis (star-wheel axis) in real time, feeding signals back to the drive control system. It is a critical component for ensuring the accuracy of high-speed pick-and-place operations and is classified as a precision optical assembly.
Maintenance Notes
During installation, the gap between the read head window and the incremental disk must be precisely adjusted to 1.5 mm; improper handling can damage the incremental disk, leading to counting errors. When purchasing, ensure the full suffix (e.g., -01, -02) is verified to confirm compatibility with the specific machine model (such as the SIPLACE D4/D4i).
