Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The WLL180T-M is the device-level element in a SICK limit switch installation. It receives the field signals and control supply listed above — 12 ... 24 V DC 4) — and switches or conditions the load within the 240 V AC / 250 V DC ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides Through body / bracket support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
SICK WLL180T-M — Sensor or detector for object detection, distance measurement and status feedback on production lines. The figures below are taken from the specification table on this page for catalog number WLL180T-M; record the nameplate data of the unit being replaced before selecting an equivalent.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Q.Before ordering WLL180T-M, which rated operational voltage entry should be checked?
The rated operational voltage entry quoted above is 240 V AC / 250 V DC. Compare it with the nameplate of the installed unit before ordering.
Q.Where can I find the frequency data for WLL180T-M?
It is listed in the specification table for SICK WLL180T-M as 31.2 kHz/7.1 kHz/2 kHz/250 Hz/62.5 Hz. Confirm this figure against the unit currently in the panel.
Q.For WLL180T-M, what does the specification table state about enclosure rating?
The specification table lists enclosure rating = IP65 / IP67 (IEC 60529) for SICK WLL180T-M. Use the value as the reference when sourcing a current-production equivalent.
Q.What should I include in an enquiry for WLL180T-M?
Send the full catalog number WLL180T-M, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for SICK WLL180T-M.
Q.Can the WLL180T-M replace the unit currently installed in my panel?
Compare catalog number WLL180T-M and the ratings above with the nameplate of the installed device. A current-production equivalent is selected by function and electrical rating, not by the label alone.
