Extra Flexible AFR-ET SPC 250V PTFE Lead Wire for Compact Electronics and Medical Devices

The AFR-ET SPC is a PTFE lead wire designed for internal wiring in compact electronics where space is limited and flexibility is essential. The conductor uses extra fine stranded silver plated copper—19 strands for 30 AWG, scaling up to 315 strands for 16 AWG—delivering the flexibility needed to route through tight chassis corners, narrow cable channels, and densely packed component layouts.

Insulation is wrapped and sintered PTFE tape, producing a thin, uniform wall that maintains full -90°C to +200°C performance and chemical resistance while occupying minimal space inside enclosures. The 250V AC rating matches the internal circuit voltages of medical devices, portable instruments, and control panels.

Available in AWG sizes 30 through 16, with ten standard colors for circuit identification. For OEM applications requiring specific gauges, colors, or conductor constructions, custom options are available.

Extra fine stranded conductor – 19 strands at 30 AWG, scaling to 315 strands at 16 AWG. Delivers flexibility that standard PTFE hook-up wire cannot match, enabling tight bends and easy routing in compact enclosures.

250V AC voltage rating – Matches the internal circuit requirements of medical devices, portable instruments, and control panels. Allows for thinner insulation than 600V wire, saving valuable space.

PTFE wrapped and sintered insulation – Thin wall construction with consistent thickness. Rated -90°C to +200°C. Resists chemicals, solvents, and outgassing. More flexible than extruded PTFE.

AWG 30 to 16 range – Covers the small-gauge sizes most commonly used for internal wiring in compact electronic devices.

10 standard colors – Black, brown, red, orange, yellow, green, blue, purple, grey, white. Provides clear circuit identification for complex wiring harnesses.

Custom options available – Other AWG sizes, colors, conductor materials, or insulation types on request for OEM applications.

Medical device internal wiring – Portable patient monitors, diagnostic imaging equipment, and handheld surgical tools require lead wire that fits tight enclosures without stressing connectors. AFR-ET SPC's extra fine stranding and thin PTFE wall make it suitable for medical electronics packaging.

Compact electronic instruments – Test and measurement devices, data loggers, and portable analyzers have limited internal volume. This lead wire provides the necessary 250V rating with smaller diameter and superior flexibility for chassis routing.

Control panel backplanes – When terminal blocks are packed closely, stiff wire fights back and springs out of position during assembly. AFR-ET SPC routes easily between densely populated components and stays where placed.

Semiconductor handling equipment – Wafer transfer robots and probers require cleanroom-compatible materials. PTFE insulation generates minimal particulates, and fine stranding survives the continuous vibration of wafer transport.

Robotic end-of-arm tooling – Wrist axes and grippers need wire that flexes continuously without fatigue. The extra fine stranded silver plated copper conductor withstands millions of flex cycles in dynamic applications.

Test fixture internal connections – High-density probe arrays require wire that does not push back against delicate probe contacts. AFR-ET SPC's flexibility prevents spring-back that could lift probes or damage devices under test.

Laboratory analytical instruments – Mass spectrometers and vacuum chamber systems require low-outgassing materials. PTFE wrapped insulation meets vacuum compatibility requirements while fine stranding simplifies routing through instrument internals.

Aerospace black box internals – Flight recorders and avionics modules demand wire that fits dense connector backshells and withstands vibration. Thin PTFE insulation maximizes pin density; fine stranding provides vibration resistance.

Portable communication equipment – Handheld radios, field deployable terminals, and battery-powered devices benefit from lightweight, flexible internal wiring that conserves space for larger batteries.

Industrial sensor enclosures – Pressure transmitters, temperature monitors, and flow sensors often have compact housings. AFR-ET SPC routes cleanly between sensor elements and output terminals.

Q: What is the temperature range of this PTFE lead wire?

A: Continuous operation from -90°C to +200°C. The wrapped and sintered PTFE construction maintains flexibility at low temperatures and resists flow at high temperatures.

Q: Why does AFR-ET SPC use extra fine stranding?

A: Standard PTFE hook-up wire typically uses 7 or 19 strands per conductor. AFR-ET SPC uses 19 to 315 strands, depending on AWG size. This fine stranding makes the wire significantly more flexible, allowing it to bend tightly around chassis corners and fit through narrow cable channels.

Q: How does wrapped PTFE compare to extruded PTFE?

A: Wrapped PTFE produces a thinner, more uniform insulation wall with better flexibility. Extruded PTFE tends to be stiffer and thicker for the same voltage rating, making wrapped PTFE the better choice for compact electronic packaging.

Q: Can I get a sample before placing a production order?

A: Yes. Sample lengths are available upon request. A nominal fee may apply, which is fully deductible from your first bulk order.

Q: What is the lead time for custom orders?

A: Standard colors and AWG sizes in stock ship within 7 business days. Custom colors or non-standard constructions typically require 10-15 working days after order confirmation.
