Overview
The Honeywell 58426 digital magnetic speed sensor is a precision variable reluctance sensor (VRS) designed for aerospace and industrial speed measurement applications. This sensor combines active electronics with traditional variable reluctance principles in a compact package, delivering a digital square-wave output suitable for immediate integration into control systems.
Key Features
- Internal Signal Conditioning – Converts analog waveforms to digital signals internally, eliminating the need for external interface circuitry
- Constant-Amplitude Output – Produces stable square-wave signals ideal for digital and logic control applications
- Variable Reluctance Design – Detects ferrous gear teeth or encoded targets without external power to the sensing element
- Connector or Cable Termination – Available with leads or MS3106A connector for aerospace environments
- Wide Supply Voltage Range – 5 to 15 Vdc operation with minimal current draw
