Autonics MP5Y-4N Pulse Meter

The Autonics MP5Y-4N is a high-performance digital pulse meter with a five-digit, 14 mm LED display that reads from -19999 up to 99999. It supports 16 operation modes, including Frequency, Revolutions, Speed, Cycle, Time, Ratio, Density, and Length/Interval measurements, making it suitable for tachometer, counter, and process-monitor tasks in industrial settings. It accepts both voltage input (PNP) and no-voltage input (NPN), is powered from 100–240 VAC (50/60 Hz) with an optional external 12 VDC supply up to 80 mA, and front IP54 protection. Input timing for solid-state inputs reaches up to 50 kHz on input 1 and 5 kHz on input 2 (with certain modes up to 1 kHz), while a contact input runs up to 45 Hz; the unit weighs about 230 g (excluding packaging).
