The Cable Your Cleanroom Has Been Waiting For.
Standard cables contaminate. Junkosha's EHF-03 LO is engineered with zero plasticizers, no outgassing additives, and a PTFE fluoropolymer construction that keeps your chamber clean — and your process running.
What Your Current Cable Is Doing to Your Process
An unclean cable doesn't fail loudly. It fails quietly — contaminating chambers, extending baking cycles, and shortening the life of expensive equipment.
The Contamination You Can't See
Every standard cable in your chamber is slowly releasing plasticizers, lubricants, and binder residues. You can't smell it. You can't see it. But your yield data can.
The Baking Cycle That Never Ends
Before every production run, your cables need hours in the outgassing chamber. That's downtime you pay for in energy, in throughput, and in scheduling complexity.
The Stiffness Problem
Fluoropolymer cables should be clean — but most are also rigid and prone to cracking under repeated flex. When a cable fails inside a vacuum chamber, the cleanup cost dwarfs the cost of the cable itself.
EHF-03 LO: Engineered Clean. Ready for Your Chamber.
Junkosha selected every material in the EHF-03 by a single principle: what goes into your chamber must not contaminate it. No plasticizers. No additives. From raw material to packaging.
Zero Outgassing Additives
No plasticizers, no lubricants, no residues that migrate into your process gas or vacuum environment. From material selection to manufacturing, packaging, and shipping — everything is clean.
Fraunhofer Certified
Zero particles/cft at 0.1–5.0 μm particle sizes across all test velocities. Not estimated. Tested. Fraunhofer particle certification with documented results across all operating conditions.
Flexible Despite Being Fluoropolymer
Dramatically improved bend compliance vs conventional PTFE — survives repeated repositioning and moving stage components without cracking. Junkosha has manufactured cables like this for 40+ years.
Cleanroom Class 10–1000 Compatible
Packaged and shipped clean, ready to install without additional preparation. Compatible with semiconductor fab, FPD, analytical equipment, and space hardware environments.
LO + SLO — Two Variants
LO (EHF-03): for atmospheric to medium vacuum — cleanrooms, process equipment, analytical instruments. SLO (EHF-032): for high/ultra-high vacuum — EUV lithography, SEMs, mask inspection equipment, and satellites.
Technical Specifications

Frequently Asked Questions
What's the difference between the LO and SLO variants?
LO (EHF-03) is designed for atmospheric to medium vacuum environments — cleanrooms, process equipment, analytical instruments. SLO (EHF-032) is for high to ultra-high vacuum: EUV lithography tools, SEMs, mask inspection equipment, and satellites.
Is this cable flexible enough for moving stages?
Yes. Junkosha specifically engineered the flex life to meet semiconductor moving-stage requirements. It outperforms conventional fluoropolymer cables in both bend compliance and cycle life.
Can I get custom core counts and shielding?
Yes. Junkosha manufactures to customer specifications. Round and flat configurations available with customizable core counts and shielding options. Contact Koto Electronics with your requirements.
What certifications does it carry?
Fraunhofer particle test (zero particles/cft), meets NASA outgassing standards, cleanroom Class 10–1000 compatible.
Is this cable available from stock in Israel?
Koto Electronics is the authorized Israeli representative for Junkosha. Contact us to check availability and lead times for your specific configuration.
Does the cable support carbon emission reduction?
Yes. By reducing the need for long pre-production baking cycles, EHF-03 saves time and energy consumption — which Junkosha cites as a direct environmental benefit toward carbon emission reduction goals.
Your Chamber Deserves a Cable That Won't Contaminate It.
Every hour your chamber sits in a baking cycle is an hour not producing. EHF-03 LO reduces that time — and keeps your environment clean for the full cable service life.
