SS541AT General Description

SS5 Series Hall effect position sensors are operated by the magnetic field from a permanent magnet or electromagnet. The small SOT89 style package surface mounts on PC boards and flexible circuits. The SS5 uses a industry standard "gull-wing" design which makes it less susceptible to "solder bridging" and allows increased circuit board density. The SS5 series package can accommodate larger IC's than SS1 and allows for fourpin designs.

The integrated circuits are designed to provide predictable performance over the full temperature range of -40 to +150°C. Bipolar, unipolar and latching magnetics are available. The SS5 has the same footprint and pinout as the industry standard SOT-89. It will replace Honeywell SS1 Series and any equivalent SOT-89 sensors from other suppliers with minimum or no design changes.

On-board regulation provides extremely stable operation over the full supply voltage range of 4.5 to 24 VDC(SS51T) or 3.8 to 30 VDC(SS500). Current consumption is a low 10 mA maximum at 40°C and is typically 7mA or less at room temperature and above. SS5 sensors are capable of continuous 20 mA sinking output, and can withstand temporary current as high as 20 mA maximum (SS51T) or 50 mA maximum (SS500). They can use existing power supply sources in most applications, and can be directly interfaced with many electronic components without buffering or compensation circuitry.

SS5 Series sensors are supplied on tape and reel for high-volume, automated pick and place equipment. Each reel contains 1,000 sensors. MICRO SWITCH supplies bar and ring magnets for operating Hall effect sensors. Bar magnets can operate any Hall effect sensor. Ring magnets are magnetized on the outside diameter with alternating North and South poles. They are particularly useful with bipolar sensors and rpm measurement.
