factory-tuned flat type micro load cell — optimized for OEM integration.
The WST101 is a micro load cell. All figures on this page come from the factory parameter sheet — what you read here is what ships.
Contact our engineers for the complete datasheet and design-in support.
WST101 flat type micro load cell, which is a specialized electronic sensor designed to measure force or weight in compact devices. This specific component features a metal plate with a unique cutout pattern that allows for slight deformation under pressure. Attached to the hardware are four colored wires—typically red, black, white, and green—which transmit electrical signals to a controller or display. Its square frame includes mounting holes at each corner, suggesting it is intended for integration into digital scales or portable weighing equipment. By converting mechanical stress into a measurable voltage change, this small part serves as the critical interface between physical mass and digital data.
