Ultrasonic Proximity Sensors Quick Selection Guide

Ultrasonic Proximity Sensors Technical Definitions and Terminology Sound Wave Ultrasonic sensors operate by emitting and receiving high-frequency sound waves. The frequency is usually in the order of 200 kHz, which is too high for There are two basic modes of operation: opposed mode and diffuse (echo) mode. In opposed mode, one sensor emits the sound wave and another, mounted opposite the emitter, receives the sound In diffuse mode, the same sensor emits the sound wave and then listens for the echo that bounces off an object. Emitted Wave Sensing Range The sensing range is the distance...

Ultrasonic Proximity Sensors Bulletin 873P Analog or Discrete Output Plastic Barrel Bulletin 873P Ultrasonic Sensors are self-contained solid-state devices designed for noncontact sensing of solid and liquid objects. They are diameters that are constructed from PBT plastic and meet IP67 enclosure standards. The electronic circuitry is potted to protect against shock, These sensors are available with either analog or discrete output types and three different sensing ranges. Analog model selection includes Discrete models have a normally open adjusting the sensing range to ignore background...

Ultrasonic Proximity Sensors Bulletin 873P Analog or Discrete Output Plastic Barrel Normal Operation For normal operation do not connect the control pin. Hold and synchronize features can be used for special To inhibit sensor operation and hold the output to its present state connect the control pin (2) to OV DC. The sensor will not transmit or receive ultrasonic pulses until this voltage is removed from the control pin. Switching output models will be latched and analog output models will hold their value during this period. ultrasonic pulses between several sensors connect the control...

Ultrasonic Proximity Sensors Plastic Barrel Bulletin 873P Programmable Ultrasonic Sensors are self-contained solid-state devices designed for non-contact sensing of solid and liquid objects. They are available with a 30 mm barrel diameter that is constructed from PBT plastic and meets IP67 enclosure standards. The electronic circuitry is potted to protect against shock, These sensors have two programmable setpoints with sourcing (PNP) outputs that can be configured for either normally open or normally closed operation. They also feature a The slope of the analog output is scaled between the...

Ultrasonic Proximity Sensors Plastic Face/Threaded Nickel-Plated Brass Barrel The Bulletin 873C ultrasonic sensor has the ability to detect solid and liquid targets from a distance of up to 1 m versions: a background suppression unit with analog voltage output or a standard diffuse model with a digital The analog model provides an output voltage that varies linearly with the target distance and an adjustable background suppression feature. For many applications, such as monitoring the level of water in a tank, ultrasonic technology allows a single device to do a job that would otherwise...

Ultrasonic Proximity Sensors 873E RightSound ™ Opposed Mode Clear Object Sensing System 18 mm Right Angle Plastic Housing Opposed Mode RightSound Bulletin 873E sensors are opposed mode ultrasonic sensors consisting of an emitter and a receiver. The receiver is microprocessor based to provide advanced temperature stability and noise immunity. Precise tuning of the receiver to the emitter minimizes interference from ambient noise sources. The emitter volume control allows the operator to correctly adjust the volume for the sensing distance (distance from the emitter to the receiver) and other...
