MQ-W20C-DC12-24VEM: delivery record

July 4, 2026

Historical parts record: Photos and notes below belong to this record. Confirm the offered unit’s full model, condition and available test evidence before ordering.

The source identifies MQ-W20C-DC12-24VEM and records four new domestic replacement sensors with a two-year warranty on 28 November 2025. It also lists SUNX and Japan, creating a provenance conflict within the same note. The first photograph shows four wired sensor bodies beside SUNX-marked cartons.

Identification and delivery details

SUNX lettering and small model/circuit printing appear on the sensor backs in photograph 1, but the full code and electrical lines are not clearly readable at this view. Photograph 2 shows a yellow circular feature in the black housing and its fixed cable. Neither image is a detection or output test.

The source's domestic-replacement statement is retained alongside its Japan wording. SUNX printing does not authenticate Japanese original manufacture, and the Panasonic naming in the title is not used to resolve that contradiction. Exact provenance requires separate confirmation for the offered units.

Four bodies are visible, consistent with the source quantity, without proving individual condition or warranty coverage. The 0.5 kg field has no specified packing basis. The title's triple-beam description, the old claim of discontinuation and predictive-maintenance language are not established by the two reviewed views.

Request the full MQ-W20C-DC12-24VEM label and replacement documentation. Confirm wiring, mounting and optical requirements against the installed sensor rather than treating printed branding as proof of original supply.

Resolve the domestic-replacement/Japan wording and confirm the two-year supplier warranty. Request a detection test under the intended conditions and identify the manufacturer of the offered replacement.
