Photocell Sensor for Heidelberg SM102 CD74 SM52 Printing Machinery Parts

This photocell sensor is offered for compatible Heidelberg SM102, CD74 and SM52 printing machinery. It is intended for replacement during servicing when the existing photoelectric sensor is faulty or damaged.
Photocell sensors use light-based detection to provide a signal to the machine’s control system. Their specific detection task depends on the sensor type and its installation position within the press.
The pictured assembly includes a rectangular sensor housing, attached cable and circular metal connector. Correct replacement requires matching the original sensor’s part number, operating voltage, output type, sensing arrangement, mounting dimensions and connector pin configuration.
Compatibility can vary between machine versions. Share the original sensor label, Heidelberg machine model and part number for assistance with selecting the appropriate replacement.
