Parallel beam sensor / Parallel beam sensor
Product Categories Parallel beam sensor
The SM18H-IL series parallel beam sensors are characterized by high accuracy, wide measurement range, long lifespan, simple structure, good frequency response, and the ability to operate under harsh conditions. They are also easy to miniaturize, integrate, and diversify, and are mainly suitable for small-platform electronic scales such as electronic price-computing scales and weighing scales.
