Electronic switches [india] provides inductive proximity switches. These inductive proximity switches are non-contact type sensors in nature and are used to sense ferrous materials. Function of these inductive proximity switches are like as soon as a metal part comes in the range of these sensors, it gives output which can be used for controlling further processes. These are either ac type or dc type. Dc type sensors are three-wire type with supply voltage of 5 to 30 v dc, whereas ac type sensors are two-wire with supply voltage of 90 to 240 v ac. Both the types are available in different housing diameter to suit different applications. The length fixed is 65 mm. In applications of space constraint extended type can be offered in which the sensing part is available in m6 or m8 housing. Output offered is either npn or pnp and either no/nc. They are available in flush-type or non-flush type. There is an led indication for pnp or npn output. Red colour led for pnp type and green colour led for npn type.
