The Littelfuse 55320 Series Flat Pack Linear Hall Sensor is an absolute position sensor designed for linear measurement up to 30mm. Utilizing non-contact magnetic Hall effect technology, it offers analog or PWM output signals, providing immunity to mechanical wear and contamination common in wiper-based products. This sensor is engineered for harsh environments with an operating temperature range of -40C to 105C. It features automotive-grade EMI/EMC and reverse battery polarity protection, along with commercial-grade 20 AWG-TXL automotive wire and optional Molex sealed connectors. Common applications include hydraulic cylinder position, transmission shift position, valve position, seat position, and automation controls within vehicle and industrial segments.
