946 Series
Ultrasonic Sensors
Teachable 30 mm
Diameter, Precision Digital
Outputs
DESCRIPTION
The 946 Series provides a compromise between easy usage
and advanced features. Adjustment is easily done by auto-
tuning. By inserting a plug with four positions one can program
the sensor in a matter of seconds; the parameters are stored in
a non-volatile memory (EEPROM).
