C-7233 Sensor is completely free of mercury and therefore does not contain toxic parts, or that could harm the environment. The lean of the sensor is activated when its angle will vary in relation with its installation position. The first sign of vibration will operate it, regardless of position. It is very sensitive and it can be used as movement sensor. The lineal acceleration sensor will close its contact if it receives an impact superior to 5G and it opens the contact if the level decreases. The C-7233 movement sensor is omni-directional, and it will open the contact if it is in vertical position and it close the contact when it come back or it is inclined more than 60º.
