The BES021E is the device-level element in a Balluff industrial component installation. It receives the field signals and control supply listed above — the rated supply — 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 control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides 40x40 PBT square housing, non-flush, connector M12x1 male 4-pin support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Balluff BES021E Inductive Proximity Sensor. See the manufacturer product information for this catalog number.
Cross-check the ratings above with the installed device before confirming the order.
Q.Which value is published under response time for catalog number Q40KFU-PAC30F-S04G?
For Q40KFU-PAC30F-S04G, response time is given as <= 50 Hz switching frequency. Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering Q40KFU-PAC30F-S04G, which enclosure rating entry should be checked?
The enclosure rating entry quoted above is IP67 (IEC 60529). Confirm this figure against the unit currently in the panel.
Q.Where can I find the sensing distance Sn data for Q40KFU-PAC30F-S04G?
It is listed in the specification table for Industrial Q40KFU-PAC30F-S04G as 30 mm. Use the value as the reference when sourcing a current-production equivalent.
Q.Can the Q40KFU-PAC30F-S04G replace the unit currently installed in my panel?
Compare catalog number Q40KFU-PAC30F-S04G 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.
Q.How do I confirm compatibility of Q40KFU-PAC30F-S04G before ordering?
