BC304 and BC305 crown the series BC300 in the higher measuring ranges: the cell BC304 for compression; the cell BC305 for tension and compression. These button load cells find applications for general purpose on machines, where the very low profile and the extreme compactness are important; moreover their small dimensions and easy construction bring them competitive compared to other larger cells with the same measuring ranges.
The BC300 series button load cells are designed for applications where a very low profile and extreme compactness are required. They are suitable for static and dynamic measurements, compression, tension, and multipoint setups in machines and robotics.
The document provides detailed technical specifications for models BC301‑BC305, including measuring ranges, sensitivity, error limits, excitation voltage, overload capacity, electrical connection, and overall dimensions.

The series provides ranges from 0–30 kg (Al) up to 100 kg (Fe) for BC302, and similar ranges for other models as listed in the specifications.
The typical sensitivity is 2 mV per volt of full‑scale excitation.
A 5 V DC or AC supply is standard, with a maximum of 6 V allowed.
The cells can withstand overloads up to 1.5 times their full‑scale rating.
