It features a sealed sensing face that protects internal components from lubricants, fluids, and contaminants commonly found in industrial and heavy-duty machinery. The sensor utilizes a high-resistance precision coil to generate strong voltage output across a wide range of speeds and gear configurations. Compliance with MIL-STD-202F vibration requirements ensures consistent operation in mechanically demanding environments. Key Features High Voltage Output: Produces a minimum of 60 V peak-to-peak signal for reliable speed detection in electrically noisy systems. Sealed Front-End Design: Protects the sensing element from oils, debris, and moisture in harsh environments. High-Resistance Coil Construction: Coil resistance of 910–1200 ohms supports strong signal generation at low surface speeds. Wide Temperature Capability: Operates reliably from -55 °C to 150 °C across diverse industrial conditions. Standard Threaded Mounting: 5/8-18 UNF-2A thread with 3.0-inch length enables secure and repeatable installation. Broad Gear Compatibility: Designed for gear pitches of 24 DP or coarser, supporting multiple mechanical designs. High Frequency Response: Capable of sensing rotational speeds with response frequencies up to 15,000 Hz. The MA243SAN delivers the reliability and precision required for speed sensing applications in harsh industrial and heavy-equipment environments.
