Features and Applications
Desco is a leading manufacturer of ESD control products for the electronics industry. With 6 manufacturing locations in the USA, Desco offers a broad line of products including wrist straps, foot grounders, mats, shielding bags, floor finish, ionization, workstation monitors and test equipment.
When grounded properly, wrist straps are the most common grounding devices used to control static charges. Wrist straps safely remove static charge from the operator to protect your ESD susceptible components and products. The primary cause of static charge generation is people. ESD susceptible parts and products face their greatest threat from workers handling parts.
Desco refuses to put your product at risk. Desco wrist straps are hand made using only high quality fabrics and stainless steel materials. This allows us to control the quality and offer a consistent reliable and offer a consistent reliable product that meets industry as well as UL requirements.
Static charge is produced by the contact and separation of materials: shoes and floors, clothes and the human body, parts being moved on or from surfaces. The generated charge will reside on the body until it is discharged – the familiar electric shock “zap” that all of us have experienced. However, one can’t feel a static discharge of less than 3,000 volts. Some modern semi-conductor components can be damaged by static charges as low at 30 volts! It’s the heat and light of this “zap” that does the damage. Properly fitted and grounded wrist straps prevent any static charge from building up so there’s no discharge to your products. The wrist strap is your first line of defense against ESD.
All Desco wrist straps, when properly worn and grounded, fulfill the requirements of ANSI/ESD S20.20, paragraph 220.127.116.11.Made of relaxed retraction strength black PVC, Desco's 09480 6 ' coil cord will not interfere with wearer's movements. Eliminates intermittent failures that occur with less durable single and dual wire cords. Improved snap design. Stronger strain relief and snap retention for long life; low profile keeps cord from being disconnected. Superior banana plugs with patented contour supported spring, fits into all standard banana jacks > 0.157" ID Greater retention force; cords won't fall out and put your parts at risk. Spring loaded 4mm stainless steel constant contact snap. Provides constant electrical contact. Tensile strength at each end in excess of 30 lbs. One megohm series resistor at snap end. To protect operator from accidental contact with equipment line voltage, meets UL & OSHA minimum requirement.
