Model GLL-20 Analog Output Shock Sensor

Application

  • Vibration control for industrial machinery
  • Vibration monitoring for electronic devices
  • Monitoring of impact on the game console
  • Security of mechanical instruments
  • Security of structures

Features

  • Measurement of impact and output as linear analog values
  • Output a direct current of 0 V to 3 V proportional to the impact (g) generated by an impact frequency of 30 Hz to 1kHz.
  • By taking the sensor output to an external comparator IC and adjusting the voltage level of the other input of the comparator IC, it is possible to use the sensor so that the shock sensitivity to be detected can be freely adjusted.

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.

Usage precautions

  1. The product can resist during 2000 hours to vibrations of 10 Hz (0.3 g) to 55 Hz (9 g) with a peak-to-peak amplitude of 1.5 mm in the impact detection direction. However, check sufficiently the vibration resistance of the sensor if complex frequencies or large vibrations should be constantly applied to the sensor.
  2. If the sensor is subject to thermal shocks, its detection sensitivity will vary as long as it is subject to the sudden temperature change. Check the environment before using the sensor.
  3. Do not use the sensor when stress is applied on the harness connected to the connector, or when the harness is subject to impacts and oscillates.
    Otherwise, the wires may break or the sensor may malfunction. Secure the harness connected part so that it does not oscillate and no stress is applied on it.
  4. For other precautions, refer to “General Precautions” for shock sensors.
