Where it sits in the control system
The II5987 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 non-flush mountable 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 II5987
IFM II5987 — 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 II5987; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Overload capacity: yes — Record it with the other nameplate data when sourcing a replacement.
- Response time: <= 1500 Hz switching frequency — 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.
- Rated torque: 50 Nm — Verify it in the project documentation before confirming the order.
Cross-check the ratings above with the installed device before confirming the order.
Common questions about II5987
Q.Before ordering II5987, which communication ports entry should be checked?
The communication ports entry quoted above is IO-Link. Compare it with the nameplate of the installed unit before ordering.
Q.Where can I find the response time data for II5987?
It is listed in the specification table for IFM II5987 as <= 1500 Hz switching frequency. Confirm this figure against the unit currently in the panel.
Q.For II5987, what does the specification table state about rated torque?
The specification table lists rated torque = 50 Nm for IFM II5987. Use the value as the reference when sourcing a current-production equivalent.
Q.How do I confirm compatibility of II5987 before ordering?
Match the catalog number II5987 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
Q.Can the II5987 replace the unit currently installed in my panel?
Compare catalog number II5987 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.
