TKD KAWEFLEX 3340 Industrial Data Cable

Description

Product Introduction & Engineering Value

The TKD KAWEFLEX 3340 belongs to TKD’s flexible industrial cable range and is intended for applications where signal and data conductors must tolerate repeated movement. Published TKD-related listings identify 3340 SK-TP-C-PUR configurations with a 2×(2×0.25 mm²) construction.

For procurement, the critical point is that 3340 is a cable family/designation, not enough information by itself to establish every electrical and mechanical specification. TKD products are offered in numerous conductor sizes, shielding configurations, jacket materials, and lengths. The complete jacket marking should therefore be captured before approving a replacement.

Technical Specifications

A TKD product listing specifically identifies KAWEFLEX 3340 SK-TP-C-PUR 2×(2×0.25 mm²), while another industrial cable listing identifies TKD 3340 in the same general product family.

About ZL68061

ZL68061 should not automatically be interpreted as the complete TKD model number.

The same marking appears on other TKD cable listings. For example, a KAWEFLEX 6430 SK-C-PUR listing carries ZL68061, while a TKD 2458 cable listing also shows ZL68061. This strongly indicates that the marking is associated with certification/approval or production identification rather than uniquely defining the cable construction.

Field Application & “Trench” Experience

The KAWEFLEX 3340 family is appropriate for automation installations where a conventional fixed installation cable would be exposed to repeated movement.

Typical applications include:

• CNC machine cable carriers
• Robotic equipment
• Automated assembly machinery
• Pick-and-place systems
• Moving sensor and actuator connections
• Industrial communication wiring
• Flexible machine interconnections

Maintenance Scenario

A common failure mode in moving-machine installations is not immediate conductor breakage. Instead, repeated bending can progressively damage shielding, increase contact resistance, or create intermittent communication faults.

For a 3340 replacement, technicians should therefore compare the conductor count, pair construction, shield arrangement, jacket material, and bend requirements, not simply purchase another “3340” cable.

Transparency SOP: QA & Testing

For New Surplus or replacement cable inventory, inspect the actual cable before cutting it to length.

1. Read the complete jacket marking.
2. Confirm TKD / KAWEFLEX identification.
3. Confirm the 3340 designation.
4. Record the complete conductor-size marking.
5. Verify the number of pairs/conductors.
6. Inspect the shielding construction.
7. Confirm PUR versus PVC or another jacket material.
8. Measure conductor continuity.
9. Test insulation resistance where appropriate.
10. Check shield continuity.
11. Inspect the jacket for cuts, flattening, cracking, or chemical damage.
12. Confirm supplied length before installation.

For New Surplus material, retain a photograph of the jacket marking and reel label as part of the receiving record.

Veteran’s Tech Trap Guide

Trap 1 — Ordering only “3340”

TKD’s cable families contain multiple constructions and sizes.

PRO TIP: Purchase against the complete printed jacket specification, not simply KAWEFLEX 3340.

Trap 2 — Assuming ZL68061 defines the cable

It does not appear to uniquely identify the cable construction. The same ZL68061 marking is found alongside other TKD cable families.

PRO TIP: Treat as a secondary identification/approval marking until the complete TKD datasheet confirms its meaning.

Trap 3 — Confusing fixed-installation cable with continuous-flex cable

A cable that electrically matches the required conductor arrangement may still fail mechanically if its bending characteristics are unsuitable.

PRO TIP: For drag-chain or robotic applications, verify the manufacturer’s specified flexing/bending conditions before substitution.

Trap 4 — Ignoring shielding

For industrial communication circuits, shield construction can directly affect EMC performance.

PRO TIP: Match the original shield topology, termination method, and cable construction rather than selecting a cable based only on conductor count.

Dynamic FAQ

What is TKD 3340?

KAWEFLEX 3340 is a TKD flexible industrial cable designation. Published listings include a 3340 SK-TP-C-PUR 2×(2×0.25 mm²) configuration.

What does ZL68061 mean?

ZL68061 appears as a marking on multiple TKD cable products, including KAWEFLEX 6430 and TKD 2458. It therefore should not be used alone to identify the exact cable construction.

Is 3340 a communication cable?

It can be used for industrial data/communication applications depending on the exact 3340 construction. The specific electrical protocol suitability should be determined from the complete cable specification.

Is the 3340 suitable for drag chains?

The KAWEFLEX product family includes cables specifically designed for flexible machinery and moving applications. However, the exact 3340 variant should be checked for its specified flexing duty before installation in a continuous-motion drag chain.

What should I verify before ordering?

Verify:

• TKD Kabel GmbH
• KAWEFLEX 3340
• Complete jacket marking
• Conductor count
• Conductor cross-section
• Pair configuration
• Shield construction
• Jacket material
• Voltage rating
• Temperature range
• Minimum bending radius
• Required cable length
• New Surplus condition and warranty

Procurement identification:
TKD Kabel GmbH KAWEFLEX 3340 — ZL68061 marking

Because 3340 TKD ZL68061 does not uniquely establish the complete cable construction from the public evidence available, the full jacket marking or reel label should be treated as the final identification authority.
