Circuit Board Mounted Load Cell - S420

Click image for larger view

 

The Model S420 load cell is a new circuit board mounted load cell intended for applications requiring accurate measurement of full scale forces of up to 25 pounds-force. It can be soldered directly into a rigid printed circuit board. A 5,000Ω bridge offers low power consumption for extended battery life in portable products.

Ideal for use in medical instrumentation, laboratory use, or office equipment force measurement applications. The load cell can be customized for additional full-scale ranges, heights and load button
