ELECTRICAL 207 ELECTRICAL 1. ULTRASONIC SENSOR: FUNCTION: The sensor working principle is same as echo depth sounding. The sensor transmits the ultrasonic pulses. SPECIFICATIONS: Sensor type Ultrasonic with signal processing unit Supply voltage 6 to 10 Vdc ,-ve gnd Operating temperature -30 °c to + 80 °c Storage temperature -40 °c to + 85 °c Communication with controller Bidirectional Beam Angle for Y=200 Sensor ( 2 and 3) Horizontal – 90° Vertical - 50° Beam Angle for Y=600 Sensor ( 1 and 4) Horizontal – 120° Vertical - 80° LOCATION: It is located on the rear bumper. Specifically adapted mounting brackets are used to secure the sensors in their respective positions in the bumper. System has two types of sensors. They have different detection angles and different size of ribs for fitment. Appropriate slots are provided in bumper housing where these are to be fitted. A. Narrow Beam Sensor (Middle sensors): Bumper mounting location: 2 and 3 B. Wide beam Sensor (Extreme sensors): Bumper mounting location: 1 and 4 CONNECTOR DETAILS: PINOUT DETAILS: PIN NO DESCRIPTION 1 Sensor supply 2 Communication line 3 Gnd
