Vibration sensor CMVT-QR20-IOLX3-H1141, 16 g, 0...320 mm/s, 3-axis, IO-Link, -40...+85°C, M12, IP69K

CMVT-QR20-IOLX3-H1141 is a condition monitoring vibration and temperature sensor measuring acceleration and velocity over three axes plus the housing temperature. It is intended for rotating machine parts where rising vibration indicates bearing wear, imbalance or shaft misalignment, so the deviation is caught before a failure.

• Measuring range: acceleration 16 g RMS (6.6 kHz sampling), velocity 0...320 mm/s RMS @ 78 Hz, temperature -40...+85°C; resolution 0.01 g and 0.01 mm/s
• Accuracy: velocity linearity deviation ≤ ±1 % @ 78 Hz, acceleration ≤ ±3 % @ 78 Hz; repeatability ≤ ±5 % @ 78 Hz
• Outputs: pin 4 - IO-Link or SIO, pin 2 - SIO; two PNP/NPN switching outputs in SIO mode; IO-Link COM 3 (230.4 kBaud)
• Supply: 18...30 VDC (IO-Link), 10...30 VDC (SIO), consumption < 50 mA
• Protection: against wire break and reverse polarity
• Housing: rectangular QR20, Ultem plastic, 71.6 x 62.6 x 20 mm
• Environment: IP68/IP69K, pollution degree 3, shock 200 g (4 ms), vibration 20 g
• Connection: M12 x 1 male connector, 4-pin

Over IO-Link the output quantity is selectable - acceleration or velocity, RMS or peak-to-peak - and the switching thresholds are set there. Thresholds can be parameterised to the ISO 10816-3 machine classes or defined freely. A green LED shows the supply and, when flashing, active IO-Link communication; two yellow LEDs show an exceeded threshold.
