Adaptaflex, 21 mm Nominal Diameter, Polyamide, Black

ABB Series PF Conduit, 21mm Nominal Diameter, 50m Length - PFCH21/BL/50M

This conduit is a 21mm polyamide tubing designed to protect and route cables in industrial and transport environments. Supplied in a 50m length and finished in black, it provides a protective channel for electrical and electronic wiring where mechanical resilience and environmental resistance are required.

Features & Benefits

• IP66-rated enclosure keeps water and dust out under harsh conditions
  Withstands temperatures down to -50°C enabling cold‑environment use
  High abrasion resistant construction reduces maintenance frequency
  Halogen free self‑extinguishing material lowers fire‑hazard emissions
  Low smoke low toxicity formulation improves evacuation safety
  UV resistant and corrosion resistant for prolonged outdoor durability

**Applications**

• Suitable for cable routing on automation cabinets and panels
  Ideal for wiring in rolling stock and rail vehicle interiors
  Used with electrical control systems in manufacturing plants
  Can be used for conduit protection in outdoor sensor installations
  Used for cable management on mechanical drive assemblies

What mechanical stresses can it tolerate during installation?

The material exhibits high mechanical strength and flexibility, allowing it to resist fatigue from bending and repeated movement during installation and service.

How does it behave in fire scenarios with confined spaces?

Its self‑extinguishing and halogen‑free composition produces low smoke and low toxicity combustion products, reducing harmful emissions in enclosed areas.

Is the product suitable for marine or chemically aggressive atmospheres?

The polyamide formulation is corrosion resistant, making it appropriate for environments where exposure to moisture and corrosive elements is likely.

Can it be used where frequent flexing occurs around equipment?

Yes
the conduit offers high flexibility and anti‑fatigue properties to accommodate repeated bending without premature failure.
