Specifications

Key Features

• OFX-100 ESD fabric — lightweight 2.3 oz/yd² construction; provides static dissipative protection without bulk or discomfort during extended wear
• ESD knit cuffs — conductive knit wrist cuffs maintain ground continuity from the garment through to the operator’s wrist strap connection point
• Knee-length coverage — protects clothing and provides full upper-body ESD shielding from shoulders to knees
• 3 patch pockets — practical storage for tools, pens, and small components during assembly work
• Snap front closure — quick donning and doffing; no metal zippers that could scratch or damage sensitive assemblies
• Lapel collar with set-in sleeves — professional appearance suitable for customer-facing cleanroom and lab environments
• Fast static decay — dissipates 5,000V charge to 500V in under 0.1 seconds; meets ESD garment performance requirements

Industries & Applications

• Electronics manufacturing — ESD protection for PCB assembly, SMT lines, and component handling at ESD-protected workstations

Frequently Asked Questions

What is OFX-100 fabric and why is it used for ESD garments?

OFX-100 is a lightweight, woven ESD fabric that incorporates conductive fibers in a grid pattern to provide static dissipative surface resistivity of approximately 10⁵ Ω/sq. It is widely used in electronics manufacturing ESD smocks because it provides reliable ESD protection while remaining comfortable and breathable for all-day wear.

Do ESD smocks need to be worn with a wrist strap?

Yes — ESD smocks are one layer of an ESD control program, not a standalone solution. For ANSI ESD S20.20 compliance, the smock should be worn in conjunction with a wrist strap (or ESD footwear on a conductive/dissipative floor) to maintain a continuous ground path from the operator to ground.

Can ESD smocks be laundered?

Yes — OFX-100 ESD smocks are designed to be launderable. ESD performance should be periodically retested after washing, as repeated laundering can affect surface resistivity over time. Follow Tech Wear’s care instructions and retest per your ESD program’s garment verification schedule.

Is the LOC-33 compliant with ANSI ESD S20.20?

The LOC-33 is designed to meet the garment requirements of ANSI ESD S20.20 ESD control programs. Surface resistivity of ≈10⁵ Ω/sq and static decay performance (<0.1 sec from 5,000V to 500V) are consistent with S20.20 garment specifications.
