Optoelectronic switches

Optoelectronic switches are used for the detection of limit levels in liquids. This detection is mostly independent of the physical characteristics of the liquids, such as refractive index, density, dielectric constant and conductivity.

The absence of any moving parts and the standard compact design characterise the instruments. A high media compatibility is ensured through a measuring tip from borosilicate or quartz glass and a robust stainless steel case.

Item number

What is a part / item number?

The WIKA part number is our standard numbering system used to identify a specific product configuration. This is ideal for repeat orders, as you only need to refer to the WIKA part number for a specific product. It is numeric and typically comes in 7 or 8 digits (e.g. 14149166). All of our electronic products have the part number printed or engraved on the product and identified for example as P#14149166. This is in contrast to the individual serial number which is identified for example as S#11639110000. The WIKA part number can also be found on the individual packaging, shipping box and all WIKA documents related to the order.
