Micro Parallelogram Load Cell LSM 250

The Micro Parallelogram Load Cell LSM 250 is designed for ultra-compact, high-accuracy tension and compression measurement in OEM and embedded systems. With side-mount construction, built-in overload protection, and excellent linearity in a small footprint, this sensor is ideal for applications where space is limited but performance is critical.

Key Features & Benefits of the Micro Parallelogram Load Cell LSM 250

  • Compact & Space-Saving Design – With dimensions of ~1.49″ in length, 0.38″ width and 0.93″ height, the LSM250 fits into tight assemblies without compromising function.

  • Side-Mount Capability – Easily integrates into OEM setups via side mounting, optimizing layout flexibility.

  • Built-In Overload Protection – Offers 50× to 200× built-in overload protection, helping protect the sensor during installation or transient loads.

  • High Accuracy & Stability – Nonlinearity, hysteresis, and nonrepeatability of ±0.05 % of full scale, keeping measurements consistent and precise.

  • Flexible Output & Integration – Supports analog outputs (mV/V, VDC) and digital interfaces (SPI, RS-232, UART, BLE) for modern system compatibility.

  • Low Power Consumption – Well-suited for battery-powered or energy-conscious embedded systems.

  • Rugged Construction – Crafted from aluminum with precision strain gauge sensing, the LSM250 is built for reliable, repeatable service.
