Introduction

Thank you for purchasing an IRU ultrasonic sensor from APG. We appreciate your business! Please take a
few minutes to familiarize yourself with your IRU and this manual.

The IRU series is APG’s line of general purpose ultrasonic sensors. With a choice of operating ranges

from just a few inches to as far as 50 feet, the IRU product line is designed to t a wide range of industrial
automation applications. Sensor adjustments, such as sensitivity and ltering options, are made by

interfacing the sensor to a PC using an RST module and APG’s free Windows based programming software.
IRU sensors incorporate internal temperature compensation for increased accuracy under varying
environmental conditions. The sensors are housed in PC/PET or UV resistant ABS to seal out moisture and
resist a wide range of chemicals.

Reading your label

Every APG instrument comes with a label that includes the instrument’s model number, part number, serial
number, and a wiring pinout table. Please ensure that the part number and pinout table on your label
match your order. The following electrical ratings and approvals are also listed on the label. Please refer to

the Certicate of Compliance and Declaration of Conformity at the back of this manual for further details.
