Sub-Miniature Donut Load Cell LTH150

Key Features & Benefits of the Sub-Miniature Donut Load Cell LTH150

• True Through-Hole or Donut Design – Allows a load path (shaft, bolt, rod, etc.) to pass through the center, ideal for applications like measuring bolt preload or clamping force.

• Ultra Compact / Low Profile – Height only ~0.16 in (4.1 mm), outer diameter ~0.50 in (12.7 mm).

• Wide Capacity Range – Available in capacities from 5 lb up to 250 lb (≈ 22 N to 1,100 N).

• Low Deflection & Fast Response – Deflection ~0.0006 in (≈ 0.015 mm) at rated load ensures fast, accurate readings.

• Good Overload Protection – Safe overload rating ~150% of rated output to help protect against transient overloading.

• Precision Performance – Nonrepeatability ±0.1% of RO, nonlinearity and hysteresis per spec table.

• Rugged Construction & Good Environmental Suitability – 17-4 PH stainless steel body, IP64 protection, operating temperature –60 to +200 °F (–51 to +93 °C).

• Low Power & Compact Wiring – 1000 Ω bridge resistance, 34 AWG 4-conductor braided cable, 5 ft length standard.

Ordering & Configuration Tips

If you would like to learn more about this product or would like to place an order, please contact us.

When ordering an LTH150, consider:

1. Inner hole (I.D.) needed to pass your bolt, rod, or shaft — the sensor must fit your load path.

2. Capacity required — choose a model that exceeds your maximum expected load with margin.

3. Cable length or custom connector options if the standard 5 ft is too long/short.

4. Calibration and certification needs (compression calibration, traceability, etc.).

5. Mounting and alignment — ensure the sensor mounting does not impose side loads or bending moments.
