DESCRIPTION

The OM3105P is a hybrid integrated circuit intended for inductive proximity detectors in a tubular construction, especially the M5 hollow stud. The circuit performs a make function (version 1): when actuated, the current flows through the load, which can be for example a LED or an optocoupler. It is also possible to perform a break function when using version OM3115P.

FEATURES

? Extra small dimensions (3 x 20 mm max.)

? Wide supply voltage range (6 to 35 V)

? Supply current typical 1.5 mA (output stage switched off)

? High output current (250 mA max.)

? RC filter on the supply lines

? PNP output transistor protected against transients from the inductive load

? Circuit protected against wrong polarity connection of the supply voltage

? Electronic short-circuit protection

? Detection distance adjustable by a chip resistor (Rd), type 1206

? Only a simple coil in one part is required; e.g. the OM2860 requires a coil in two parts

? Hysteresis adjustable by a chip resistor (Rh), type 0603, for using the OM3105P with other then M5 coils

? Status of the output is shown by a yellow or red LED mounted on the substrate surface

? The OM3105P is also available without a LED, but with an output pad for external LED connection

? A version with a NPN output transistor is available (OM3105P).
