SM451R Datasheet PDF - Honeywell

●The SM451R is an ultra-sensitive Magnetoresistive Sensor designed for manufacturers who need a durable and reliable speed or position sensor for large air gaps or small magnetic fields in standard power (typically 3 to 24Vdc) applications. The standard power series IC with solid state design offers ultra-high sensitivity of 11G maximum, making it the highest sensitivity sensor in its class for standard powered applications. The magnetoresistive sensor ICs, respond to either a North or South pole applied in a direction parallel to the sensor. They do not require the magnet polarity to be identified, simplifying installation.

● Omnipolar sensing activates with either pole from a magnet
