Selection
Head revision

Cables and components for capacitive nozzle-to-sheet distance sensing. We identify the required assembly by connectors and head revision.

For a cable, send photos of both ends, its length and the head model. For an electronic module, provide its own part number and the error description.

What it is used for

Sensor cables and height-sensing components

The sensor line carries the signal from the lower head assembly to the height-control system. Unstable height can involve the ceramic, nozzle, contacts or settings, not just the cable. Identifying the faulty component first avoids replacing working assemblies at random.

How to select the right part

Height-sensing cables depend on head revision: BM111 connector types changed over time. Cable length alone does not identify the part. Photographs of both ends and the head's date or serial identification distinguish otherwise similar versions.

How to select the right part

Photograph both connectors closely. SMA and SMB have different connections even when the cables look similar.

Confirm the manufacture date or head revision: BM111 heads use different sensor cables.

Include the error code and when it occurs. After repair, check and calibrate according to the system instructions.

Ask about height sensing

Send the machine and head model, photographs of the markings and part, its dimensions and the quantity required. If replacing a faulty assembly, briefly describe the symptoms. Price and lead time on request. We check compatibility and confirm the required version before ordering.
