Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.

Where it sits in the control system

The WLL180T-P474 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.

Selection notes for SICK WLL180T-P474

SICK WLL180T-P474 — 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-P474; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.

• Frequency: 31.2 kHz/7.1 kHz/2 kHz/250 Hz/62.5 Hz — Record it with the other nameplate data when sourcing a replacement.
• Mounting: Through body / bracket — Confirm the revision of the installed unit before a like-for-like replacement.
• Enclosure rating: IP65 / IP67 (IEC 60529) — Use it as the reference when cross-checking a current-production equivalent.
• Weight: Approx. 25 g — Verify it in the project documentation before confirming the order.

For a discontinued unit, match function and electrical ratings rather than the label alone.
