Hybrid integrated circuits for inductive
proximity detectors
Preliminary specification
OM3105P
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).
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.
Available versions:
OM3105P: pnp output; make function
OM3115P: pnp output; break function
OM3105N: npn output; make function
OM3115N: npn output; break function
OM31.5./0: for external LED connection.
