SETechSETech's MP-981 is magneto-type detector using a hall element which suitable for RPM measurment from ultra low speed to high speeds. Magnet-type detectors use an internal hall element, a permanent magnet, DC Amplifier, and voltage regulator and respond to flux (i.e., the resistance value changes in response to flux changes), so that a rectangle waveform is derivable from ultra low speed all the way through high speeds. | | | SPECIFICATIONS | Detection Method | Hall element | measurement range | 1Hz~20kHz(using a60P/R gear, 1~20,000 r/min, with an output waveform duty cycle is 50%±20%) | Detection gear | Strong magnetic materials(modulus 0.5~3, tooth width 3mm or greater | Gap between detector and gear | | Power supply used | DC 12V±2V(0.5Vp~p or less ripple) | current consumption | 40mA or less(12V, at 25℃) | Otput waveform | Low level;+0.5V or less, High level;5V±0.5V rectangular waveform(With no load) | Output impedance | Approx. 330Ω | Output type | Floating groung | Protective circuit | Power supply polarity and output short protection | Operating temperature range | -10℃~+70℃ | Protective circuit | -20℃~+80℃ | Matching connector | 6-pin connector (type R04-PB6F plug) | Allowable vibration(during operation) | double-ended 1.2mm at 30Hz in X, Y, and Z direction for one hour each. | Allowable shock(non-operating) | 490m/ | | in X and Y direction each 3 times. | | Withstand voltage | 1.DC250V, 1min.(between shield and signal cable)2.dc205V, 1min.(between shield and sensor head) | Interface indicator | YD-10, YD-20, YD-30 | weight | Approx.80g (including two mornting nuts) | Accessories | Mounting nuts(2) | | | | | |
