873M Ultrasonic Sensor

General purpose ultrasonic sensor. Nickel-plated brass 18 mm cylindrical or right-angle threaded barrel provides ease of mounting and reduces installation time. Discrete (PNP) models feature normally open/normally-closed functions. Window teaching allows sensing range to be defined inside a user-taught sensing area for both discrete and analog models. The user can achieve superior background suppression. Teaching of the sensor can be accomplished by remote teach or optional programming cable. Bright LED's allow the user to monitor power, output and margin from any direction reducing time required for setup and troubleshooting.
