Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The LK-H028 is the device-level element in a Keyence 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 <= 440 V AC 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 Diffuse reflective support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Keyence LK-H028 — 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 LK-H028; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
Cross-check the ratings above with the installed device before confirming the order.
Q.For LK-H028, what does the specification table state about mounting?
The specification table lists mounting = Diffuse reflective for Keyence LK-H028. Confirm this figure against the unit currently in the panel.
Q.Which value is published under operating temperature for catalog number LK-H028?
For LK-H028, operating temperature is given as -25...+60 °C. Use the value as the reference when sourcing a current-production equivalent.
Q.Before ordering LK-H028, which weight entry should be checked?
The weight entry quoted above is Approx. 230 g (including the cable). Check the revision of the installed unit if the catalog number has been superseded.
Q.How do I confirm compatibility of LK-H028 before ordering?
Match the catalog number LK-H028 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 LK-H028 replace the unit currently installed in my panel?
Compare catalog number LK-H028 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.
