Specifications per the Omega LC305/LC315 Series datasheet (catalog pages F-33 to F-34), reviewed 2026-11-03.
Omega's LC305 series consists of heavy-duty miniature compression load cells with a 2 in. (51 mm) diameter stainless steel body. The LC305-300 is the cable-style model rated for 300 lb (1,334 N), with a built-in load button, eight tapped mounting holes in the base and a 10 ft (3 m) shielded cable. Its small size and low profile suit test benches, prototype structures and industrial weighing applications.

Key Features
Built-in load button
An integral load button with a 0.43 in. (10.9 mm) spherical radius takes the compression load and simplifies installation.
Tapped mounting holes
Eight 10-32 UNF holes, 0.40 in. (10.2 mm) deep, are equally spaced on a 1.687 in. (42.8 mm) diameter in the base for secure fixturing.
5-point calibration included
Each cell comes complete with a 5-point NIST-traceable calibration (0%, 50%, 100%, 50%, 0%) and 59 kΩ shunt data.
0.25% interchangeability
Rated output is 2 mV/V (±1%) with 0.25% interchangeability and ±2% FSO zero balance.
Stainless steel, IP65
Stainless steel construction with an IP65 protection class, rated for operation from -50 to 225 °F (-46 to 107 °C).
Overload margin
Safe overload is 150% of capacity and ultimate overload is 300% of capacity.
