ESIGNED FOR THE
Electrical Motor
Another advantage for Hall-effect sensors is the low power consumption, which results from no bias current being required by
the permanent magnet and the sensor drawing only 5 mA (typical) of supply current (I
OPTEK uses a high density molded plastic to encapsulate the Hallogic® lead frame and chip. Both the density and the transfer
molding process results in a dirt and moisture barrier effective enough to pass Military standard 883. The sensor passes “pressure
cooker” and similar moisture and temperature testing procedures to ensure a reliability product.
In addition, the lead frame is designed with superior thermal characteristics for maximum reliability at the ten TTL load capability
of the device.
The dimensional outline of the package and the precise placement of the Hall element is standard. This design allows for the
superior, temperature compensated OPTEK device to be specified for instant replacement. A significant upgrade in performance
can be achieved without costly redesign and retooling.
Because the Hallogic® Hall-effect Sensor is smaller than conventional emitter-detector pairs, it will more easily fit into areas with
small size constraints.
Hallogic® Hall-effect Sensors are virtually immune to environmental contaminants. They are rugged and suitable for use under
severe service conditions. Even in the toughest environment, the Hallogic® sensor will exhibit excellent magnetic sensitivity to
provide reliable, repetitive operations in close tolerance applications. These devices are excellent choices for DC motor,
automotive applications, robotic and heavy machinery sensing applications, or for any application in a harsh environment where
optoelectronic devices are unsuitable.
OPTEK offers the customer the same custom assembly capability they have come to expect from the Optoelectronic division.
Custom designed sensors with Hall-effect devices and magnets, long lead wires, special connectors, etc., are available. With
OPTEK’s complete plastic tooling and molding operations, Hall-effect sensors are available in a wide variety of hybrid packages.
