Frequently Asked Questions
What is the WP-S1P2 Flexible Electrical Conduit-stainless steel square lock with PVC jacket?
The WP-S1P2 series is a miniaturized stainless steel flexible conduit with square lock profile and protective PVC outer jacket. It combines exceptional corrosion resistance, IP66 water and dust protection, fire retardancy, lightweight construction, and compact size (1.5-16.1mm ID), making it ideal for signal wire protection in robots, automation, and tools exposed to moisture.
What are the advantages of the PVC jacket?
The PVC jacket provides comprehensive protection: water and splash resistance (IP66), dust barrier, fire retardancy (self-extinguishing), electromagnetic interference (EMI) shielding, improved durability, visual color identification, and environmental protection. It transforms the bare conduit from IP40 to IP66 rated.
What size range is available?
Flexible Electrical Conduit WP-S1P2 offers 22 ultra-compact sizes ranging from 1.5mm to 16.1mm inner diameter. The comprehensive range includes P015034S1P2 through P161205S1P2, allowing precise matching to any signal wire bundle, from the smallest sensor cables to larger robot motor wires.
What is the IP rating?
Flexible Electrical Conduit WP-S1P2 achieves IP66 rating, providing complete protection against dust ingress and powerful water jets from any direction. This makes it suitable for robots in wet manufacturing areas, outdoor automation equipment, and applications with spray or splash exposure.
What temperature ranges are available?
Flexible Electrical Conduit WP-S1P2 offers two temperature range options: standard -20℃~+80℃ for most automation applications, or extended -40℃~+105℃ for extreme cold and moderately high-temperature environments. Specify your requirement when ordering.
Is the PVC jacket fire retardant?
Yes, the PVC jacket features self-extinguishing properties, meaning it will not continue burning when the ignition source is removed. This critical safety feature is essential for robots and automation equipment in manufacturing facilities with fire safety regulations.
What color options are available?
Black and grey are the standard PVC jacket colors. Both provide excellent UV resistance for indoor and controlled outdoor environments. Other colors are available by special request for organizational identification or circuit color-coding in complex automation systems.
What is the bending radius and flexibility?
Flexible Electrical Conduit WP-S1P2 features high flexibility with bending radii ranging from ≤18mm (smallest 3mm sizes) to ≤105mm (largest 16.1mm size). This exceptional flexibility allows installation in ultra-compact geometries, narrow channels, and complex routing paths in robotic arms and automation equipment.
What is the tensile resistance?
Tensile resistance ranges from ≥35kg (smallest 3.5mm size) to ≥120kg (largest 16.1mm size). This ensures structural integrity and durability under mechanical stress, vibration, and repetitive flexing common in robotic applications and portable equipment.
What applications is Flexible Electrical Conduit WP-S1P2 ideal for?
Flexible Electrical Conduit WP-S1P2 is designed for signal wire protection in industrial robots, factory automation systems, portable and handheld tools, CNC equipment, access control systems, security systems, outdoor automation equipment, and any application requiring water resistance, fire protection, and compact dimensions.
Can UV resistance be added?
Yes, UV resistance can be added by special order for outdoor automation applications. This is important for equipment exposed to prolonged sunlight, as it prevents PVC degradation and maintains long-term durability and protection properties.
Why choose Flexible Electrical Conduit-stainless steel with PVC jacket?
The combination delivers maximum protection: stainless steel provides superior corrosion resistance and durability, while the PVC jacket adds water barrier, dust protection, fire retardancy, and impact resistance. This is superior to bare stainless steel for wet environments or PVC alone for mechanical durability.
How does Flexible Electrical Conduit WP-S1P2 compare to bare WP-S1-1?
Flexible Electrical Conduit WP-S1P2 adds protective PVC jacket for IP66 water protection, fire retardancy, and EMI shielding, but operates -20℃~+80℃ (or -40℃~+105℃). WP-S1-1 bare stainless steel is IP40 with extended -40℃~+350℃ range. Choose WP-S1P2 for wet/humid environments, WP-S1-1 for high-temperature control areas.
What outer diameter specifications with the jacket?
The PVC jacket adds approximately 1.4-3.5mm to the outer diameter. For example, the 1.5mm ID size has OD of 3.4mm with jacket, the 5mm ID has 7.8mm OD, and the 16.1mm ID has 20.5mm OD. These specifications are critical for space planning in compact robotic installations.
Is WP-S1P2 RoHS compliant?
Yes, Flexible Electrical Conduit WP-S1P2 is fully RoHS compliant, ensuring no hazardous substances are used in manufacturing and meeting international environmental regulations.
What packaging quantities are available?
Flexible Electrical Conduit WP-S1P2 is available in rolls of 100 meters for most sizes (1.5-10mm ID) and 50 meters for larger sizes (11.5-16.1mm ID). Custom lengths can be cut to specific project requirements for batch orders.
What related configurations are available?
Flexible Electrical Conduit WP-S1P2 is the stainless steel + PVC jacket version. Related configurations include: WP-S1-1 (bare stainless steel), WP-S1-2 (retractable stainless steel), WP-S1SB (stainless steel + stainless steel braiding), WP-S1TB (stainless steel + tinned copper braiding), WP-S1P2SB (stainless steel + PVC jacket + stainless steel braiding).
What makes the square lock profile special?
The square lock profile provides exceptional mechanical strength, superior flexibility while maintaining structural integrity, excellent impact resistance, superior light weight, and consistent geometry. Combined with stainless steel, it delivers unmatched durability for miniaturized signal wire protection.
Why is this ideal for industrial robots?
Flexible Electrical Conduit WP-S1P2 combines ultra-compact size for tight robot joint integration, high flexibility for complex arm routing, stainless steel durability for thousands of motion cycles, IP66 protection from coolant spray and cleaning water, fire-retardant jacket for factory safety compliance, and exceptional abrasion resistance for repeated flexing.
Can custom specifications be ordered?
Yes, custom configurations are available for special requirements including extended UV resistance, custom colors, specific jacket materials, custom lengths, and combinations with braiding for EMC shielding.
