Application fit

Is MPY-S / MPYC-S / MPYCY-S right for your machine?

The hyphenated `-S` series (`MPY-S`, `MPYC-S`, `MPYCY-S`) encloses each individual pair (or triad) in its own metallic screen and numbered identification tape, preventing mutual crosstalk between mixed 4–20 mA, thermocouple, RTD and pulse tachometer signals on board ships.

Fixed installation

Suitable

Multi-pair marine instrumentation, main engine exhaust/bearing sensors, cargo radar gauging and ECR marshalling.

VFD inverter to AC motor screened feeder

Suitable

Individual pair screens plus outer wire-braid armour (MPYC-S / MPYCY-S) suppress both inter-pair crosstalk and VFD noise.

Trailing & towing

Not suitable

Fixed shipboard installation cable; not designed for dynamic trailing duty.

Use LiYCY (TP)

Energy chain / drag chain

Not suitable

When only a single collective screen is needed over all cores, select MPYS / MPYCS / MPYCYS.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does the hyphenated '-S' mean in MPY-S, MPYC-S and MPYCY-S?
In JIS C 3410 nomenclature, '-S' with a hyphen indicates that each twisted pair (or individual core) is enclosed in its own metallic electrostatic screen and insulating number tape before the pairs are cabled together. By contrast, 'S' without a hyphen (MPYS, MPYCS, MPYCYS) denotes a single collective screen around the whole bundle.
When do shipboard engineers specify MPYCY-S over MPYCYS?
Specify MPYCY-S when a single multi-pair home-run cable carries heterogeneous signals — for example, mixing millivolt thermocouple/RTD loops, 4–20 mA transmitters and 24 V digital pulse tachometers — where capacitive crosstalk between pairs inside the cable must be completely blocked.
How are the individual pairs identified during termination?
Each pair uses colour-coded +90 °C EP-rubber cores (typically white and black) wrapped in its metallic screen and an outer polyester/textile tape printed with the pair number (1, 2, 3…).
Which mechanical outer protection should I select: MPY-S, MPYC-S or MPYCY-S?
Select MPY-S (PVC outer sheath, unarmoured) for internal bridge and control-room consoles; MPYC-S (exposed wire-braid armour) for dry machinery spaces; and MPYCY-S (wire-braid armour + outer PVC oversheath) for engine rooms, pump rooms and weather decks.
