Installation Instructions for the SS340RT and SS440R Series Unipolar Hall-Effect Digital Position Sensors GENERAL INFORMATION CAUTION ELECTROSTATIC DISCHARGE DAMAGE This component is sensitive to electrostatic discharge (ESD). Take normal ESD precautions in handling this product to prevent ESD-induced damage and/or degradation. Failure to comply with these instructions may result in product damage.

The magnetic field strength (gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a uniform magnetic field. NOTICE SOLDERING/ASSEMBLY CAUTION IMPROPER SOLDERING * Ensure leads are adequately supported during any forming/shearing operation so that they are not stressed inside the plastic case. * Limit exposure to high temperatures. * Do not wave solder the SS340RT. Failure to comply with these instructions may result in product damage. SS340RT Series: Use an infrared reflow process with temperatures of 245 C [473 F] peak for 10 s max. SS440R Series: PC board wave soldering temperature is 250 C to 260 C [482F to 500 F] peak for 3 s max. Figure 2. Current Sinking Output Block Diagram Sensing and Control Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will the device necessarily operate at absolute maximum ratings.
