Miniature S-Beam Load Cell 201

The FUTEK LSB201 is a high-end miniature S-Beam load cell built for demanding force sensing in both tension and compression modes. Compact but rugged, it delivers excellent performance, fatigue resistance, and overload protection—all in a small, precise package. It’s especially suitable where space, weight, and durability are constraints.

Key Features & Benefits

  • Fatigue Rated Construction – The Miniature S-Beam Load Cell 201 is designed to last through 100 million fully reversing fatigue cycles, delivering long-term stability even in dynamic applications.

  • 17-4 PH Stainless Steel S-Beam Design – The flexure is made from precipitation-hardened stainless steel for high strength, hardness, and corrosion resistance.

  • Wide Capacity Range – Models of the Miniature S-Beam Load Cell 201 are available from 250 g up to 100 lb (~2.5 N to ~444 N), making this versatile for light to moderate force/weight applications.

  • High Overload Protection – Safe overload capacity is high: up to 1800% of rated output (RO) for the smallest capacities (~250 g), 1000% RO for mid-ranges (1-25 lb), and 200% RO (tension only) for higher capacities (50-100 lb). This helps protect the sensor from accidental overloading.

  • Excellent Accuracy – Nonlinearity, hysteresis typically ±0.1% of rated output; very repeatable and low deflection (~0.003-0.005 in depending on capacity) ensures precise measurements.

  • Compact Footprint & Lightweight – 0.75 in height × 0.30 in width × 0.65 in length (~19.1 mm × 7.6 mm × 16.5 mm), weighing around 0.8 oz (≈ 22.6 g). Fits well into tight spaces.

  • Robust for Harsh Conditions – The Miniature S-Beam Load Cell 201 has a wide operating temperature range (-60 to +200 °F / -50 to +93 °C), resistant to vibration and shock per relevant standards.

  • Cable & Connection – The Miniature S-Beam Load Cell 201 comes standard with a 5 ft (≈1.5 m), 4-conductor spiral-shielded silicone cable; female threads on both ends (M3×0.5) facilitate versatile mounting.
