Product Description

​The Omron E4PA-LS50-M1-N is an ultrasonic displacement sensor designed for precise non-contact measurement of various objects and liquids. It offers a sensing range between 50 mm and 500 mm, with a dead band distance of 0 to 50 mm. The sensor features a response time of 63 ms maximum and operates with a supply voltage between 10 to 30 VDC, consuming up to 1,800 mW. It provides both current (4 to 20 mA) and voltage (0 to 10 V) analog outputs. Additionally, the sensor includes protective features such as load short-circuit protection and mutual interference prevention, allowing up to five sensors to operate in close proximity.
