LSLR Ultra-Low Range Accelerometer

Highlights:

The LSLR is a very rugged, ultra-low, single-axis accelerometer designed for peak performance in extreme conditions. The fluid damped mechanism delivers superior noise rejection in high shock and vibration environments as well as excellent output stability. Units are available with a 6-pin connector, pin-terminals, or flying leads. Available outputs include ±5V, 0-5V, and 4-20mA. Custom input ranges, filters, and temperature sensor are also available on request.
