factory-direct digital load cell, built to the application-specific capacity and accuracy your project requires.
The WST1206 is a digital 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.
WST1206 Canbus or RS485 output signal digital single point load cell, Compared to analog sensors, this series of digital sensors primarily integrates a digital transmitter, allowing the load cells to directly output standard RS485 or Canbus digital signals. Each sensor boasts high precision and high resolution, requires no additional calibration, and can be directly used with downstream equipment.
Since eccentric load compensation is pre-installed at the factory (compliant with OIML R60 standard), installation is quick; a single sensor is sufficient to build a complete scale.
This series of sensors can be used not only in stainless steel waterproof scales, process weighing control in the chemical, food and pharmaceutical industries., but is also widely used in various smart IoT products, such as smart shelves, vending machines, and RVM (Recycling Management System) automatic recycling equipment.

Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
On-board ADC + digital output (RS485 / Modbus RTU / CAN) lets the WST1206 drop straight into smart weighing terminals without external instrumentation.
RS485 / Modbus
EtherNet/IP, Profinet and Modbus TCP variants of the WST1206 connect directly to plant PLCs for in-line filling, dosing and checkweighing sequences.
Profinet ready
OPC UA and MQTT variants push weight data from the WST1206 straight into MES / SCADA / cloud dashboards — no signal converter box required.
