| Parameter | Specification |
|---|---|
| A — Measurement type | 01: V (velocity); 02: G (acceleration); 03: D (displacement) |
| B — Vibration range | V: 01 = 0–10 mm/s; 02 = 0–20 mm/s; …; 09 = 0–90 mm/s; G: 01 = 0–10 g; 02 = 0–20 g; …; 09 = 0–90 g; D: 01 = 0–100 μm; 02 = 0–200 μm; …; 09 = 0–900 μm |
| C — Mounting | 01: M10×1.5; 02: M8×1.25; 03: magnetic base; 04: custom |
| D — Cable length | 01: 1 m; 02: 2 m; …; 10: 10 m |
| E — Connection | 00(K): direct cable; 01(K): circular connector. K denotes optional armor. |
| F — Relay | 00: no relay output; 01: relay output |
Only explicitly printed codes are listed. Ellipses do not confirm the omitted intermediate codes.
Dimension drawing labels
5/8-24UNEF circular connector; overall height 83.50; lower height 69.00; outside diameter φ34.00; base width 32.50; mounting thread M8×1.25.
These are the legible labels in the catalog drawing. The bare numbers do not each carry a unit. Their dimension datums and applicability to the selected configuration require confirmation; do not apply one illustrated geometry to every ordering option.
Frequency and dynamic-range limitations
The frequency-range lower endpoints are printed without their own units. A lower limit of 10 Hz has not been confirmed by this reference. The dynamic range is explicitly printed as less than 70 dB; it has not been changed to a greater-than specification.
