FAQ

Questions engineers ask first

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

What does each code letter in RE-2Y(st)Y and RE-2Y(st)Y PiMF stand for?
'RE' denotes a process instrumentation and computer cable; '2Y' specifies solid polyethylene (PE) core insulation; '(st)' indicates a static Al/PET foil screen with tinned copper drain wire; 'PiMF' (Paar in Metallfolie) adds an individual foil screen around every pair; and the final 'Y' designates a flame-retardant PVC outer sheath.
Why is PE insulation (RE-2Y(st)Y) preferred over PVC insulation (RE-Y(st)Y) for intrinsically safe Ex-i and HART loops?
Polyethylene has a relative permittivity of εr ≈ 2.3 compared with εr ≈ 4.5–6.0 for PVC, cutting mutual capacitance below 100 nF/km (vs 200–250 nF/km for PVC). In Ex-i circuits governed by IEC 60079-14, total cable capacitance (Cc) and inductance-to-resistance ratio (L/R) must stay below the safety barrier's maximum allowable Co and Lo/Ro limits.
When should I specify PiMF (individual + collective screening) instead of collective screening only?
Collective screening (OS) protects the entire cable against external power-frequency and VFD noise and is ideal for single-pair field drops or homogeneous 4–20 mA analogue trunks. Specify PiMF when a multi-pair trunk mixes high-frequency pulse/frequency signals, HART digital bursts, and low-level millivolt signals where pair-to-pair capacitive crosstalk must be ≥ 60 dB attenuated.
When should I switch from RE-2Y(st)Y to RE-2X(st)Y or RE-2X(st)H?
Thermoplastic PE (2Y) softens above +70 °C. If the cable runs near steam tracing, hot process vessels, or high ambient zones requiring a +90 °C continuous conductor rating and +250 °C short-circuit rating, specify XLPE-insulated RE-2X(st)Y (PVC sheath) or RE-2X(st)H (LSZH sheath).
