Carrollton, Tex. TT Electronics OPTEK Technology has developed a rugged Hall-effect sensor capable of delivering accurate position sensing over a wide range of temperatures, including the most severe environmental and temperature conditions, and operating over a broad range of supply voltages, which makes them suitable for military and space applications.
The bipolar latching sensors, designated the OMH3075B and OMH3075S series, contain a Hallogic monolithic integrated circuit, which incorporates a Hall element, a linear amplifier, and Schmitt trigger on a single silicon chip.
The supply voltage for the OMH3075 series devices is 4.5 V to 24 V, with up to 25 mA of sink current in the "on" state. Output characteristics are constant at switching speeds from DC to more than 100 kHz. The operating temperature range is -55°C to 125°C. Custom designs and specifications are available to meet specific individual requirements. The OMH3075 sensors are screened to the test methods per MIL-STD-883, Class B and Class S.
The sensors have a gold lead finish (a lead finish in hot solder dip can be provided) and are housed in a hermetic ceramic package. They are compatible with high temperature (260°C) soldering processes. The company said these devices are ideal for brushless DC motors, automotive applications, robotic and heavy machinery sensing applications, or for any application in a harsh environment where optoelectronic devices aren't suitable.
Typical pricing for the sensors is $17.98 each in quantities of 1,000. Delivery is 12 weeks.
