Heidelberg SM52 Sensor G2.161.1533 Ultrasonic Double Detection G2.161.1533/01

Why Upgrade Your Double Sheet Detection?
Older Heidelberg presses often rely on simple mechanical double sheet detectors, which have several drawbacks:

Manual adjustment – Must be re‑adjusted every time paper thickness changes, reducing efficiency.

High miss rate on thin paper – Easily fails to detect double sheets of thin stock, causing blanks in finished products.

Mechanical wear & drift – Vibration at high speed can cause mechanical sensors to drift, compromising reliability.

The G2.161.1533/01 ultrasonic detector solves these issues – no frequent adjustment, unaffected by paper color/thickness, non‑contact operation, no wear, and superior long‑term stability.

Installation & Setup Guide
Installation steps:
Power off the press and ensure it is in a safe condition.
Mount the detector at the standard mounting holes on the feeder board in the front lay area (SM52 has pre‑drilled positions).
Align the emitter and receiver facing each other. Tilt the sensor head at an angle of 20° to 45° perpendicular to the paper surface. Maintain a 5–15 mm gap between paper and emitter.
Connect the wiring according to the circuit diagram (emitter and receiver plugs connect directly).
Power on and test with single sheet and double sheet to verify detection.
Tuning tips:
Enable the double sheet detector function in the press configuration table.
If false alarms occur (single sheet triggers double fault), clean the sensor surface (paper dust/ink residue) and retry.
Check terminal voltage of wires 1B65/1B66 (sensor lines). Inspect for loose or corroded cables.
⚠️ Note: Installation and adjustment should be performed by a qualified press service engineer. Seek professional help if unfamiliar.
