Weight Net weight: 55 g approx., Gross weight: 80 g approx. Net weight: 35 g approx., Gross weight: 60 g approx.

Notes: 1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23℃ +73.4℉.
2) When the sensor is used as an ordinary sensor, the communication output (C/Q) provides the same output operation as the control output (DO).
3) In case of using the cable (cable length 2 m 6.562 ft).
4) This function increases the hysteresis. Check the sensing condition when using the function.
