COIL CORD, DUAL-WIRE, SNAP-ONE
, RIGHT ANGLE MONO PLUG
*U.S. Patents 6,052,053 and 6,205,408
Dual Wire Coil Cord provides redundancy; even if one conductor is
severed, operator has reliable path-to-ground with other wire.
Used with resistive loop technology continuous monitor, continuously
verifies the proper resistance to ground of the operator
Coil cord with molded 1 Megohm current limiting resistor on both ground
paths to protect user from shock due to inadvertent contact with line
voltage
28 gauge wire
3.5mm phono plug connector
Single (Snap-One) snap head allows operators to quickly and easily
attach and detach the cord from the wristband (Use Desco wristband)
Park-it feature on Snap-One molded snap head provides convenient
park station for cord when not in use. Simply insert phono plug into hole
to allow for hanging cord at workbench.
Custom manufactured right angle mono-plug reduces chance of
accidental disconnects providing more secure ground connection
Patented* dual wire technology
Superior resistor connection strain relief
Superior reliability. Greatly exceeds ESD S1.1 Bending Life Test. Tested
at over 200,000 cycles vs. the 16,000 requirement
Superior warranty - See details of 1 year Limited Warranty at
Use patented* Dual Wire Wrist Strap with Desco Dual Wire Continuous
Monitor
"If any part of the loop should open (become disconnected or have out of limit resistance),
the circuit will go into the alarm state" [ref TR20.20], nonetheless, due to the redundancy
inherent in the dual wire wrist strap design, the operator will continue to be grounded via
the second intact wire.
Per ESD Handbook TR20.20 section 5.3.9.2.2 Dual Conductor Resistance Continuous
Monitors, "This type of monitor is used with a two wire (dual conductor) wrist strap. The
wrist strap assembly consists of a two-wire ground cord and a wristband that has two
isolated halves. When a person is wearing the wrist strap properly, the monitor measures
the loop resistance consisting of one wire of the ground cord, one-half of the wristband,
the person's skin, the second half of the wristband, and a second wire in the ground cord.
If any part of the loop should open (become disconnected or have out of limit resistance),
the circuit will go into the alarm state.
ESD Handbook TR 20.20 paragraph 5.3.2.4.4 Test Frequency "Because wrist straps have
a finite life, it is important to develop a test frequency that will guarantee integrity of the
system. Typical test programs recommend that wrist straps that are used daily should be
tested daily. However, if the products that are being produced are of such value that
knowledge of a continuous, reliable ground is needed, and then continuous monitoring
should be considered or even required"
Continuous Monitors pay for themselves improving quality, productivity, eliminating wrist
strap daily testing and test result logging. Per ESD-S1.1 paragraph 6.1.3 Frequency of
Functional Testing "Daily [Wrist Strap] testing may be omitted if constant monitoring is
used."
