Multi-Mount Continuous Monitor for One Operator and One ESD Worksurface - Desco 19652

Where sensitive components are handled, a daily wrist strap test leaves gaps, because a disconnected cord can go unnoticed until the next check. The Desco 19652 Multi-Mount Monitor continuously watches the path to ground of one operator and one ESD worksurface and signals a fault visually and audibly in less than 50 milliseconds.

Key benefits

• True continuous monitoring instead of pulsed testing: Wave Distortion technology checks the path to ground and the presence of the 1 megohm safety resistor
• Gentle on components: operator test voltage of only 1.2 V peak-to-peak at 1 to 2 microamps reduces the risk of EOS
• Fast fault detection with an alarm in under 50 ms, including intermittent wrist strap connections
• Worksurface monitoring for a path to ground below 10 megohms, switchable off where no ESD mat is used
• Park snap gives about 10 seconds to disconnect or reconnect the wrist cord without a false alarm
• Mounting tabs for workbench and equipment installation, buzzer volume adjustable by trimpot

Applications

Single workstations in electronics assembly, repair and laboratories where one operator wears a single-wire wrist strap on a grounded ESD mat. For better alarm visibility the 19653 Remote Alarm accessory can be placed in the operator's field of view.

Standards

According to IEC 61340-4-6, daily wrist strap testing may be omitted when continuous monitoring is used. This supports the compliance verification records required by EN 61340-5-1.
