SCS 770102 — Dual-Wire ESD Smock, Jacket, Blue, Knitted Cuffs, 3 Pockets, Medium
The SCS 770102 is a dual-wire static control smock jacket designed for ESD-protected areas where continuous monitoring of garment-to-ground integrity is required. Unlike standard dissipative smocks, the dual-wire design uses two isolated conductive cuff paths — each bonded to a separate snap stud at the hip — that close a circuit loop through the wearer's skin when both wrists are in contact with the cuffs. This allows the smock to be monitored in real time by a dual-wire continuous monitor such as the SCS 724, verifying that the garment is properly grounded throughout the operator's shift. Constructed from a woven fabric with a minimum of 9% carbon conductive nylon fibers in a chain-link design, creating a Faraday cage effect around the torso and arms that shields ESD-sensitive items from electrostatic fields generated by the operator's clothing. Made in the USA.

Key Features
-
Dual-Wire Continuous Monitoring: Two isolated conductive cuff paths allow real-time verification of garment-to-ground integrity via a dual-wire continuous monitor (e.g., SCS 724).
-
Faraday Cage Protection: Chain-link conductive fabric shields ESD-sensitive items from electrostatic fields generated by the operator's clothing.
-
Hip-to-Cuff Grounding: Grounds the operator without a separate wrist cord — improves productivity and freedom of movement.
-
Panel-to-Panel Conductivity: Prevents isolated charged conductors within the EPA.
-
9% Carbon Conductive Nylon: Continuous, consistent charge dissipation throughout the garment's lifetime.
-
Tag-Free Neck Label: Sizing and laundering info sublimated inside the back collar.
-
Made in the USA: Manufactured in Miami, FL.
-
ANSI/ESD S20.20 Compliant: Meets Groundable Static Control Garment System requirements (Rtg < 3.5 × 10⁷ Ω).
Frequently Asked Questions
What is a dual-wire ESD smock and how is it different from a standard ESD smock?
A standard ESD smock is dissipative — it reduces charge generation but cannot be continuously monitored. A dual-wire smock like the SCS 770102 has two isolated conductive cuff paths that close a circuit loop through the wearer's skin, allowing a dual-wire continuous monitor to verify garment-to-ground integrity in real time. This is required in high-reliability ESD programs where garment grounding must be verified, not just assumed.
What monitor is compatible with the SCS 770102?
The SCS 770102 is compatible with the SCS 724 Workstation Monitor and other dual-wire continuous monitors. It pairs with SCS MagSnap® dual-wire coil cords (770110 and 770111, sold separately).
Does the SCS 770102 need a wrist strap?
No separate wrist strap cord is required. The hip-to-cuff grounding system grounds the operator through the garment itself — improving productivity and eliminating the need for a cord attached to the wrist.
How should the SCS 770102 be laundered?
Avoid fabric softeners and dryer sheets, which deposit insulative residues that degrade ESD performance. Test periodically per ANSI/ESD STM2.1 and ESD TR53 to verify continued compliance after laundering.
Is the SCS 770102 available in other sizes?
Yes — the dual-wire blue smock series is available in XS through 6XL. See the full SCS 770100–770109 size range at MTE Solutions.
