Application

Shock monitoring of machines
Crime prevention sensors (crime prevention, intrusion detection)
Shock switches

Features

The impact is measured and output as a linear analog value.
Outputs a DC voltage of 0 to 3 VDC proportional to the shock (G).
Sensitivity is reduced for high-frequency vibrations generated by the machine, preventing false detection due to these vibrations.
Suitable for monitoring acceleration, for crime prevention scenarios such as striking, breaking and displacement of objects.
By installing a lock type connector, you can prevent the connector from being pulled out due to wire routing or vibration.
A clear click feeling when mating prevents incomplete insertion.

International Standards

Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
Products is compliant to the RoHS directive.

* Please consult about "change of specification" and "request of specification" of the product.

Precautions During Use

Tighten the case with a torque of 0.32 N·m or less.
If the sensor is subject to thermal shocks, its detection sensitivity will differ for the duration of the sudden temperature change. Check the environment before using the sensor.
Do not use the sensor when stress is applied to the harness attached to its connector, or where the harness itself is subject to shocks causing it to oscillate. Otherwise, the wires may break or the sensor may malfunction.
Secure the harness lead out so that it does not oscillate and no stress is applied on it.
If the vibration frequency of the impact is low, the smoothing time will be insufficient, resulting in pulsating wave output.
For other precautions, refer to “General Precautions” for shock sensors.
