SOP400 Opto Eletronic Level Switch Characteristics ♦Reliable optical reflection technology with no moving parts ■►Accurate, repeatable switch point for a wide variety of liquids ■►Multiple output options including PNP (NO) or NPN (N/O or N/C) standard or remote controller with relay output ■►Small size is ideal where space is limited ■►Reverse polarity, short circuit and over voltage protection ♦Work temperature -40...100°C (up to 135°C upon request) ♦Class Protection IP67 (IEC 60529) The SOP400 Opto Eletronic Level Switches are used for level detection in liquids, independent of physical characteristics such as density, dielectric constant or the conductivity of the medium. The SOP400 provides an accurate, repeatable point level switch which can be mounted in any position, especially where space is limited. This unit is often the ideal solution for point level detection of all types of industrial and food grade oil products. Operating Principle: The electro-optic sensor contains an infrared LED transmitter and light receiver. Light from LED is directed into a prism which forms the tip of the sensor. With no liquid present, light from LED is reflected within the prism to the receiver. When liquid immerses the prism, the light is refracted out into the liquid. Sensing this change, the receiver actuates electronic switching within the unit to operate an external alarm or control circuit.
