OkayaAC Power-Line Noise Filter, 220 V Class, FANUC A14L-0110-0001/P — Passive EMI/RFI Line Filter for Control and Drive Cabinets

Product Description

What this part is

This is an Okaya AC power-line noise filter — a passive LC network fitted in series with an incoming AC supply. It passes 50/60 Hz power essentially untouched while attenuating high-frequency conducted noise above its cut-off frequency, in both directions: it keeps mains-borne interference out of sensitive control electronics, and it keeps the switching noise generated by drives and switch-mode supplies from being pushed back out onto the plant supply.

FANUC carries this filter under its own part number A14L-0110-0001/P, and on a FANUC machine it is the line filter at the cabinet supply.

Decoding the numbers

FPF: the Okaya filter family designation.

07: the rated-current field within the family, which matches or exceeds the current the cabinet draws.

P: the terminal and case configuration for this build.

AC220B: the voltage class, a 220 V AC line filter, with the trailing letter denoting the build variant.

A14L-0110-0001/P: FANUC’s own part number for the filter. A14L- is FANUC’s prefix for line filters, reactors and related supply-side components. A20B- is FANUC’s printed-circuit-board prefix and A86L- is its bought-in component prefix.

Current rating and grounding

A line filter is sized on current. The sizing figure is the current the cabinet draws.

Grounding is what makes the filter work. The Y-capacitors inside shunt common-mode noise to the filter’s earth terminal, so a short, wide bond to bare cabinet metal delivers the rated common-mode attenuation. The mounting position is at the point the cable enters the enclosure.

Interchange guidance

Okaya’s current catalogue lists single-phase SUP AC power-line noise filters: SUP-EP, SUP-EK, SUP-EQ, SUP-EH-EP and SUP-PH-R, built to 250 VAC with rated currents from about 1 A to 50 A. They differ in case dimensions, terminal type and mounting centres, and the current rating of this FPF07P must be read from its label before choosing one. Neighbouring FANUC supply-side part numbers in the same A14L block are A14L-0065-0001, A14L-0102-0002 and A14L-0135-0001, catalogued as search cross-references.
