BUFLEX-M Cable Equivalents & Cross-Reference Guide

Introduction to BUFLEX-M Cable Equivalents

When sourcing flexible polyurethane cables for industrial automation applications, engineers and procurement professionals often encounter multiple cable designations that appear functionally similar. The BUFLEX-M cable by TEBAOFLEX is engineered to meet or exceed the performance specifications of numerous international PUR cable brands and standards. This comprehensive cross-reference guide helps you identify equivalent cables and understand the technical basis for equivalence comparisons.

Cable cross-referencing is not simply about matching conductor size and voltage rating. True equivalence requires analysis of stranding class, insulation material, shielding effectiveness, sheath compound formulation, flex life rating, and environmental resistance. This guide examines each of these parameters to provide confident specification and substitution decisions.

International Standard Equivalents

BUFLEX-M is designed to comply with multiple international cable standards, making it a globally acceptable solution for multinational equipment manufacturers and export-oriented projects:

Brand-by-Brand Cross-Reference

The following table provides cross-reference data for common international PUR flexible cable brands. This information is based on published technical specifications and is intended as a selection guide. Final specification should be verified against the specific datasheet for your application.

Technical Basis for Equivalence

Conductor Equivalence

BUFLEX-M utilizes IEC 60228 Class 5 finely stranded conductors, which are equivalent to:

• ASTM B174: Class B (concentric) or Class C (unilay) stranding (comparable flexibility)
• IEC 60228: Class 5 (flexible) — direct equivalence
• VDE 0295: Class 5 — direct equivalence
• BS 6360: Class 5 — direct equivalence

When cross-referencing conductor sizes, note that metric and AWG sizes are not exact equivalents. The following conversion table provides the closest matches:

In general, when substituting metric sizes with AWG, the AWG cable has a slightly larger cross-section, which provides a small ampacity margin. This is generally acceptable for most applications.

Sheath Material Equivalence

The polyurethane sheath of BUFLEX-M is a polyester-based thermoplastic polyurethane (TPU). When evaluating equivalence with other PUR cables, verify the base polymer type, as different PUR formulations have significantly different properties:

For most industrial automation applications, polyester-based PUR (as used in BUFLEX-M) is the preferred formulation due to its superior mechanical strength and oil resistance. Polyether-based PUR is recommended for applications with significant water or moisture exposure where hydrolysis resistance is critical.

Flex Life Equivalence

Flex life is the most challenging parameter to cross-reference because testing conditions vary significantly between manufacturers. The following provides guidance for flex life equivalence:

• Type A (continuous flex): Cables rated for 3+ million cycles in cable chains. BUFLEX-M falls in this category.
• Type B (occasional flex): Cables rated for 100,000-1,000,000 cycles. Suitable for applications with intermittent flexing.
• Type C (fixed installation): Cables designed for static installation with no continuous flexing.

When cross-referencing cables, verify that the manufacturer’s flex life rating was determined under comparable test conditions (bend radius, travel speed, and cable carrier design). If the test conditions are not specified, contact the manufacturer for clarification.

Substitution Guidelines

Substituting Other Brands with BUFLEX-M

When replacing an existing cable with BUFLEX-M, follow these steps:

1. Verify voltage rating: Ensure the BUFLEX-M configuration matches or exceeds the original cable’s voltage rating.
2. Confirm conductor size: Match the metric or AWG size, allowing for the slight cross-section differences noted in the conversion table.
3. Check core count: Verify the number of cores matches. BUFLEX-M supports 2-60 cores (unshielded) and 2-24 cores (shielded).
4. Verify shielding: If the original cable is shielded, specify BUFLEX-M-CYC; if unshielded, use BUFLEX-M-UC.
5. Confirm environmental compatibility: Verify that the PUR sheath is suitable for the application’s chemical environment. For specialized chemicals, consult our engineering services team.
6. Check bend radius: Compare the cable outer diameter and ensure the minimum bend radius (7.5×D for flexing) is acceptable for the installation.

Dimensional Compatibility

When replacing cables in existing cable chains or conduits, verify dimensional compatibility. BUFLEX-M cables are designed with standard dimensions that are compatible with common cable chain designs.

For precise dimensional data, download the BUFLEX-M product datasheet or contact our technical team.

Quality and Certification Equivalence

BUFLEX-M cables are manufactured under ISO 9001 quality management systems and carry certifications that are equivalent to or exceed those of competing brands:

Common Cross-Reference Scenarios

Scenario 1: OEM Equipment Export

An equipment manufacturer building machines for European export needs to substitute a Lapp ÖLFLEX-450 P cable with BUFLEX-M. The substitution requires:

• Verifying core count and conductor size match
• Confirming CE marking is present on BUFLEX-M
• Checking that the PUR sheath meets the same oil resistance standards
• Ensuring the flex life rating meets or exceeds the original specification

Solution: BUFLEX-M-UC in the corresponding core count and conductor size provides direct equivalence. Request a declaration of conformity for European customer documentation.

Scenario 2: Maintenance Replacement

A maintenance department replacing a worn-out Helukabel PUR-C-JZ/O cable needs a compatible substitute that maintains the same performance characteristics.

Solution: BUFLEX-M-CYC provides equivalent shielding (tinned copper braid ≥85% + Al-poly tape), PUR sheath, and flex life rating. Verify outer diameter compatibility with existing cable chain or conduit.

Scenario 3: Cost Optimization

A system integrator seeks a cost-effective alternative to premium-brand PUR cables without compromising performance in a high-cycle cable chain application.

Solution: BUFLEX-M’s purpose-engineered construction provides equivalent or superior flex life at a competitive price point. Request flex life test data for the specific application parameters to validate equivalence.

Requesting a Cross-Reference Analysis

• Side-by-side technical specification comparison
• Flex life validation under application-specific conditions
• Chemical compatibility verification
• Dimensional compatibility confirmation
• Certification documentation for project compliance

When a cross-reference should be rejected

A similar cable name, nominal voltage or outer diameter is not enough to approve a substitute. The replacement should be rejected for further review when the original installation has continuous movement, a defined bending path, a mechanical pull, a drum or reel, shielding requirements, or a project-specific marking requirement that has not been compared.

For a reliable review, compare the original cable marking and datasheet with the actual equipment duty. If one item cannot be confirmed, document the gap in the RFQ rather than treating a product name as proof of equivalence.
