Where it sits in the control system
The II5256 is the device-level element in an IFM circuit breaker installation. It receives the field signals and control supply listed above — 10...30 V DC (IEC 60947-5-2) — and switches or conditions the load within the the rated 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 distribution boards, motor protection circuits, panel feeders, where the unit is matched to the original catalog number and the enclosure provides standard panel or DIN-rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for IFM II5256
IFM II5256 — 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 II5256; always cross-check the catalog number and hardware revision on the nameplate before placing an order.
- Weight: 275.5 g — Confirm the revision of the installed unit before a like-for-like replacement.
- Operating temperature: -25...+70 °C (IEC 60068-2-1) — Use it as the reference when cross-checking a current-production equivalent.
- Enclosure rating: IP67 (IEC 60529) — Verify it in the project documentation before confirming the order.
- Certifications: CE, cULus — Check this value against the nameplate of the installed unit before ordering.
For a discontinued unit, match function and electrical ratings rather than the label alone.
