Description

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. A red instability indicator LED is used to signal the operator when an unreliable sensing condition is present due to low or high emitter sound levels or of adverse environmental conditions. Green power LEDs indicate power status to the emitter and receiver. A yellow output energized LED indicates when the receiver output is on. Precise tuning of the receiver to the emitter minimizes interference from ambient noise sources.

A major advantage of the RightSound sensor is the emitter volume control. 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 variables of a given application (i.e., target speed and spacing, etc.). For further details on this subject, please refer to page 4 of this document, Application Information.

The sensing of clear objects, which can be difficult to do reliably with photoelectric controls, is made highly reliable with RightSound ultrasonic sensors. RightSound sensors have been designed for demanding environments, especially those of the Food and Beverage Industry. The NORYL housings are extremely rugged and are rated for 1200psi washdown and NEMA 4X and 6P standards. The acoustic faces of the emitter and receiver are made of FDA compliant silicone rubber for maximum durability and water ingress protection.

RightSounds require 10.8V DC to 30V DC power. Receivers come with both NPN current sinking and PNP current sourcing outputs. Both outputs are rated 100mA. The receiver has the ability to operate in either a normally open or normally closed mode. The modes are selected by the polarity of receiver supply voltage (see Wiring Diagrams on page 2). When the receiver is in the normally open mode, the output conducts when the receiver hears a RightSound emitter.

indicators conveniently mounted at the

When the receiver is in the normally closed mode, the output conducts when the sonic beam from the emitter is blocked or not present.
