WARNING: Not To Be Used for Personnel Protection

Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or

death. This device does not include the self-checking redundant circuitry necessary to allow its use in

personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized

sensor output condition.

Overview

The K50U is an easy-to-use ultrasonic sensor with extended range and built-in temperature compensation. This sensor is designed

to interface with a Node with 1-Wire Serial Interface. To install the sensor to either the serial Node or a cable, follow these

instructions:

1. Align the notch in the Node’s or cable’s female connector with the key in the sensor’s male connector.

2. Gently slide the sensor end into the Node’s or cable’s connector.

3. Rotate the Node’s or cable’s threaded nut to tighten the sensor down. DO NOT attempt to rotate the sensor after it is

connected to the Node’s serial port or the cable end, this will damage the sensor.

Indicator LEDs communicate the status of the sensor. The flashing green Power LED indicates the sensor is in Run Mode (the

sensor’s normal operating condition).

Sensor Configuration Tool (instruction manual 170002) and adapter cable BWA-

USB1WIRE-001 (datasheet

170020).

Principles of Operation

Ultrasonic sensors emit one or multiple pulses of ultrasonic energy, which travel through the air at the speed of sound. A portion of

this energy reflects off the target and travels back to the sensor. The sensor measures the total time required for the energy to

reach the target and return to the sensor. The distance to the object is then calculated using the following formula: D = ct ÷ 2
