The L120 Enclosed Logger is a powerful control device and fully programmable data logger, all in one compact unit.

The L120 acquires data from other devices, such as an ECU, for logging and telemetry. It can be used in a wide range of applications, either as a standalone unit or integrated with other electronic devices such as displays and PDM's.

Note: An L120 Enclosed Logger with USB Logging is also available. (Part #18045)

  • 3-axis accelerometer, detection range: +/- 5G
  • Sensor supply voltage
  • Battery voltage
Power supply
  • Operating voltage: 6 to 32 V DC
  • Operating current: 0.5 A typical at 14 V (excl. sensor currents)
  • Reverse battery protection
  • Battery transient protection
Sensor supply currents
  • 5 V sensor supply: 0.25 A maximum
  • 8 V sensor supply: 0.25 A maximum
Operating temperature
  • Internal: -20 °C to 70 °C
  • Typical ambient temperature range in free air: -20 °C to 55 °C
  • Unit size: 134.5 x 103.9 x 20.2 mm excluding connector
  • Weight 310 g
