Hall effect sensors with output proportional to supply voltage and the strength of the magnet field Single current sinking or current sourcing linear output Rail-to-rail operation provides more useable signal for higher accuracy Responds to either positive or negative gauss Good temperature stability Typical applications include; current sensor, motor control, position control, encoder, metal detection, vibration sensor etc
Honeywell Ratiometric Hall Effect Sensor, 1.5mA Switching Current, 4.5 to 10.5V DC - SS490 Series - SS495A
This ratiometric Hall effect sensor from Honeywell measures changes in the voltage of magnetic fields. It attaches to your printed circuit board (PCB) via a through-hole mounting method that creates a secure deep-pin connection. The sensor is typically paired with external magnets to trigger switching or proximity sensing without the need for physical contact with your machinery, reducing the risk of mechanical wear. As it's a ratiometric sensor, its output voltage is set by the supply voltage, so it adjusts in proportion to the strength of the magnet for heightened accuracy.
Features & Benefits
• Rail-to-rail operation strengthens received signals for better readings • Compact dimensions of 4.06 (length) x 3 (width) x 1.6mm (depth) for installation on a crowded PCB • Laser trimmed thin-film resistor for heightened precision
Applications
• Current sensors • Motor control • Position control • Metal detection • Vibration sensors
How sensitive is this sensor to temperature?
This sensor's typical sensitivity of 0.2% per degree Centigrade (°C) helps balance the positive and negative temperature coefficients to keep readings stable. It has a wide operating temperature range of -40°C to +150°C for use in extreme cold or heat.
