Note
The preprogrammed data of the sensors are stored in an
internal shift register. Strong electrostatic discharges
may change the programmed parameters. To help protect
the sensors from such disruption please follow the guidelines
below when installing the sensors.
• Place a capacitor between VDD and GND in close
proximity to the sensor.
• Use shielded, twisted pair cables whenever possible.
• Use a good power supply with adequate EMI protection.
• Connect the sensor programming voltage and clock
inputs to VDD. Connect the programming data input to GND.
Specifications subject to change without notice.
Sentron roducts are not to be used in devices or assemblies if the failure in any way of the Sentron
product could cause that device, assembly or associated system to become hazardous or unsafe.
