Bulletin 873P Programmable Ultrasonic Proximity Sensor Installation Instructions

This document provides installation, programming, and specification details for the Bulletin 873P series of programmable ultrasonic proximity sensors, which are self-contained solid-state devices for non-contact sensing of solid and liquid objects. It covers wiring diagrams, beam patterns, analog output configurations, and step-by-step pushbutton programming for two discrete PNP setpoints with either 4-20mA or 0-10V DC analog output.
