Botron B9201 – One Operator Continuous Monitor

• Single operator continuous monitor
• Designed to monitor the resistance of the operator’s path to ground
• Contains a built-in audible alarm and LED
• Supports 1 operator via single wire ESD wrist strap
• Triggers either when operator falls out of spec, becomes disconnected, or ground is lost

The Botron B9201 Single Operator Continuous Monitor is designed to monitor the resistance of the operator’s path to the ground. It comes with a built-in audible alarm and LED, triggering either when the operator falls out of spec, becomes disconnected, or ground is lost. It is a fixed resistor system and is go/no go. A full-time monitoring system is necessary to reduce latency on the assembly line.

The B9201 offers universal support for standard 4mm banana-type grounding coil cords.

Overview

Single conductor (more commonly called single wire) ESD wrist strap monitors detect capacitance. These simplified monitors sense the input connection but do not discern precision resistance. It also offers additional value by monitoring the ground connection at the mat. The built-in LED offers local visual alerts, and a small piezo buzzer offers a nice clear audible alert to the operator at the bench.

This is an entry point to monitoring personnel at the bench. If you are only verifying your Single Wire ESD Wrist Straps via an ESD tester it is possible your wrist strap may fail or the operator may exceed the allowable resistance path to ground while at the bench, exposing sensitive components to electrostatic discharge.
