  • True RMS or calculated peak output
  • Connector options: 2-pin MIL-C-5015 or 4-pin M12
  • Easily integrated into existing process control systems
  • Compact housing for applications with height restrictions
  • Manufactured in an approved ISO 9001 facilityCertifications Wilcoxon’s PCC420A series sensors provide a 4-20 mA output proportional to vibration, allowing for continuous trending of overall machine vibration. This trend data alerts users to changing machine conditions and helps guide maintenance in prioritizing the need for service. The choice of RMS or peak output allows you to choose the sensor that best fits your requirements. x (4-20 mA output type) yy (4-20 mA full scale) C (output connector) R = RMS output, acceleration P = calculated peak output, acceleration 05 = 5 g (49 m/sec2) 10 = 10 g (98 m/sec2) 20 = 20 g (196 m/sec2) 50 = 50 g (490 m/sec2) R6 = 2 pin, MIL-C-5015 M12 = 4 pin, M12 Table 1: PCC420Ax-yy-C model selection guide
