The catalog's general linearity figure and the diameter-specific errors are separate specifications. Use the error for the selected probe; do not apply the single general figure to every range. The original heading translated here as minimum target dimension has unclear terminology; confirm its meaning before specifying a target surface.
Probe ordering options
CZ9920-A□□-B□□-C□□-D□□-E□□-F□□-G□□
| Parameter | Specification |
|---|---|

Only the printed codes are listed. An ellipsis in the catalog does not establish the omitted intermediate ordering codes.
Conditioner ordering options
CWY-DO-A□□-B□□-C□□
| Parameter | Specification |
|---|---|
| A — Range | 01: 0–1 mm; 02: 0–2 mm; 03: 0–4 mm; 04: 0–15 mm; 05: 0–30 mm; 06: 0–50 mm; 07: custom |
| B — System cable length | 03: 3 m system; 05: 5 m system; 09: 9 m system |
| C — Output | 01: 0–5 V; 02: 0–10 V; 03: Modbus RTU; 04: TCP/IP |
Only the printed codes are listed. An ellipsis in the catalog does not establish the omitted intermediate ordering codes.
Range matching and selection limitations
The probe measurement table lists 12 mm and 25 mm, while the corresponding positions in the conditioner ordering table list 0–15 mm and 0–30 mm. Both values are retained; a matching probe–conditioner combination is not established by these tables. Confirm the required pairing before ordering.
The selection drawing identifies the probe, probe cable, extension cable and armor by the ordering-table letters. It does not specify additional universal fixed dimensions. The conditioner designation is printed as CWY-DO; whether the final character is the letter O or the digit zero remains unconfirmed.
