Application fit

Is MPYCY right for your machine?

MPYCY is the workhorse JIS C 3410 shipboard control cable for engine rooms, pump rooms, bilges and weather-exposed decks where the wire braid armour must be sealed against seawater, fuel oil and humidity by an extruded outer vinyl oversheath.

Fixed installation

Suitable

Engine rooms, boiler rooms, cargo pump rooms, weather decks and watertight bulkhead glands on vessels.

VFD inverter to AC motor screened feeder

With conditions

Wire braid provides mechanical and earth screening; for dedicated EMI instrumentation, select overall-screened MPYCYS.

Use MPYS / MPYCYS

Trailing & towing

Not suitable

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

Use SY Control

Energy chain / drag chain

Not suitable

Not intended for drag chains; for multi-pair analog signals with zero crosstalk, select MPYCY-S.

Use MPYCY-S Pair

FAQ

Questions engineers ask first

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

Decode the full five-letter JIS C 3410 designation MPYCY.
'M' = Multi-core control cable (250 V); 'P' = +90 °C cross-linked Ethylene-Propylene rubber (EPR) core insulation; first 'Y' = Vinyl (PVC) inner bedding sheath; 'C' = Galvanised steel or tinned-copper wire braid armour; second 'Y' = Flame- and oil-resistant Vinyl (PVC) outer oversheath.
Why does MPYCY seal better in watertight bulkhead glands than MPYC?
Because MPYC has an exposed wire braid outer surface, water can wick along the interstices of the braid if not specially sealed. MPYCY extrudes a smooth, circular PVC oversheath over the wire braid so standard marine compression glands achieve a positive watertight and gastight seal.
Can MPYCY be supplied with tinned-copper wire braid instead of steel wire braid?
Yes. Both galvanised steel wire braid (standard for engine rooms and decks) and tinned annealed copper wire braid (for non-magnetic compass zones and low-impedance earthing) are compliant with JIS C 3410.
What if my circuit also requires an electrostatic screen inside the armour?
For analog 4–20 mA, thermocouple or RTD instrumentation that requires an electrostatic copper/Al-foil screen independent of the mechanical wire braid armour, select MPYS / MPYCS / MPYCYS (overall screen) or MPY-S / MPYC-S / MPYCY-S (individual pair screens).
