Reduce the Risk of Damaging ESD Sensitive Devices in Critical Applications

Pair the EMIT ZVM Solo with the Desco Europe MagSnap 360™ Wrist Strap

The EMIT ZVM Solo utilises a steady state DC signal to provide real-time continuous monitoring. It instantaneously detects broken cords, intermittent faults, dry skin, loose bands and low resistance.

Desco Europe MagSnap 360™ Dual-Wire Wrist Straps exceed the ANSI/ESD S1.1 flex test requirements. Its 360º rotation between wristband and coil cord promotes comfort and freedom of motion. It also reduces strain on the operator's wrist.

1. MagSnap 360™ Dual-Wire Wrist Straps have a superior magnetic connection to eliminate intermittent failures that can occur in traditional snap connections.
2. MagSnap 360™ Dual-Wire Wrist Straps maintain a 1 to 5 pound perpendicular breakaway force to prevent accidental disconnects.
3. MagSnap 360™ Dual-Wire Wrist Straps have longer lifespans than traditional wrist straps with snaps and springs.
4. An important feature of the MagSnap 360™ Dual-Wire Wrist Straps is that even if one conductor is severed, the operator has reliable path-to-ground with the other wire. The Continuous Monitor used with the Wrist Strap will alarm. However, the operator will still be grounded by the other wire. So there is a significantly reduced risk of damaging the product if the operator happens to be handling and ESD sensitive component when the wrist strap fails.
5. Continuous monitors commonly apply voltage to the operator. The EMIT ZVM Solo utilises dual polarity signals which sends a positive signal via one wire and a negative signal via the other wire. These signals offset each other when they meet at the wristband and leave zero voltage applied to the operator.

"This type of monitor is used with a two wire (dual) wrist strap. When a person is wearing a wrist strap, the monitor observes the resistance of the loop, consisting of a wire, a person, a wristband, and a second wire. If any part of the loop should open (become disconnected or have out of limit resistance), the circuit will go into the alarm state." "While the continuity of the loop is monitored, the connection of the wrist strap to ground is not monitored." "There are two types of signals used by resistance based constant monitors; steady state DC and pulsed DC. Pulsed DC signals were developed because of concerns about skin irritation. However, pulse DC units introduce periods of off time (seconds) when the system is not being monitored." [ESD TR 12-01 Technical Report Survey of Constant (Continuous) Monitors for Wrist Straps]
