RS PRO Ultrasonic Block Proximity Sensor, 4 m Detection 4-20 mA, 10 → 30 V dc

Introducing the range of RS PRO Ultrasonic Proximity Sensors, ideal for obstacle detection, distance measurement and liquid and solid material sensing applications. These versatile and high-quality sensors are an essential addition to any environment where measurement of attributes like pressure, thickness, etc. are integral to business operations, like manufacturing plants and industrial environments. Thanks to the internal temperature compensation, each measurement is picked up with high accuracy, even in challenging environments where factors like dirt, dust or fog are present. Whether it’s position detection, detection of solid, liquid or powdered materials or distance measurement, with the RS PRO seal of approval, you are guaranteed a premium performance product, without the premium product price tag.

An ultrasonic proximity sensor is a non-contact device that is able to detect the presence or absence of virtually any object regardless of material. The sensors do this by emitting a high-frequency sonic pulse and monitoring the signal that is reflected back, picking up the difference in measurement, for example, if an object or obstacle is detected. An output signal is given when this happens – this is most commonly based on the measurement parameters and configuration the sensor has been set up with – and is then converted into a measurement distance for the user to evaluate.
These sensors are especially useful for production or laboratory environments where target objects and certain attributes need to be monitored for effective working and for the guarantee of quality, like measuring pressure, flow, thickness, liquid level and so much more.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards
