Honeywell FSS020WNGR

Honeywell's FSS-SMT Series force sensors are designed to be among the most reliable force sensors available, as demonstrated by a Mean Cycles To Failure (MCTF) of 20 million cycles under rated conditions at 25°C (77°F). This low-profile SMT sensor allows for automated assembly on PCBs, which typically helps customers reduce assembly costs. The FSS-SMT Series force sensors are designed to deliver accurate and reliable force sensing performance in a compact, commercial-grade package. The sensors incorporate Honeywell's sensing technology, utilizing a specialized piezoresistive micromachined silicon sensing element. The low-power, unamplified, uncompensated Wheatstone bridge circuit design provides an inherently stable millivolt output over the force range.

• SMT-compatible for automated assembly, eliminating hand soldering
• RoHS-compliant materials per Directive 2002/95/EC
• Low deflection (typically ~30μm at full scale) reduces measurement error
• Direct mechanical coupling between actuator ball and sensing element minimizes coupling error and mechanical hysteresis
• Rated MCTF of 20 million cycles at 25°C (77°F), application-dependent, providing consistent output over time and reducing maintenance or replacement
• Small footprint minimizes PCB space occupation
• Enhanced sensitivity without compromising signal integrity, reducing system noise and measurement error
• Ratiometric output accommodates supply voltage variations, reducing ratio errors
• Low supply voltage enables use in many battery-powered applications
• High ESD immunity per ESD sensitivity Class 3B (8 kV), reducing special handling during assembly
• Low sensor output sensitivity to mounting stresses
