The Autonics MP5Y-42 uses a 5-digit, 7-segment LED display with a 14 mm character height and a display range of -19999 to 99999. It offers 16 measurement modes including Frequency, Revolutions, Speed, Cycle, Time, Ratio, Density, Error, various Length measurements, Interval, Accumulation, and Addition/Subtraction, with a measurement range from 0.0005 Hz to 50 kHz, plus the 0.01 to the maximum for each time range and values from 0 to 99999 or -19999 to 99999 depending on mode. Input methods include voltage input (PNP) or no-voltage input (NPN), and it operates from 100–240 VAC at 50/60 Hz, with an external 12 VDC supply option (±10%, up to 80 mA). The main output uses a PNP open-collector configuration (HH, H, GO, L, LL). Input frequencies cover solid-state inputs up to 50 kHz (min pulse width 10 μs) and 5 kHz (min 100 μs) for the additional inputs, with certain modes allowing up to 1 kHz (min 500 μs) and a contact input up to 45 Hz (min 11 ms). Measurement accuracy varies by mode, with F1, F2, F7–F10 at FS±0.05%rdg±1 digit and F3–F6 at FS±0.01%rdg±1 digit. A prescale function provides direct input from 0.0001×10^-9 to 9.9999×10^9. The unit operates in ambient temperatures from -10 to 50°C (storage -20 to 60°C) and 35–85% RH (storage 35–85% RH). It weighs about 230 g (approximately 140 g for the main unit) and has an IP54 protection rating on the front panel.
