Force Sensing Resistors RP-S40-LT Force Sensor—

Force Sensing Resistors RP-S40-LT Thin Film Pressure Sensor

Focus on sensor Force sensing resistor

Force Sensing Resistors RP-S40-LT is a resistive varistor whose resistance value decreases as the pressure on the acting sensing zone increases.

RP-S40-LT Force Sensing Resistors

LEGACT TECHNOLOGY

Force Sensing Resistors are made of excellent mechanical properties
Polyester film, composed of highly conductive materials and nano-scale pressure-sensitive materials,
The top layer is a flexible film and a pressure-sensitive layer compounded on top, and the bottom layer is soft
film and composite on the top of the conductive circuit. Both through double-sided tape
Bonding and isolation of the sensing area. When the sensing zone is pressurized, it is on the bottom layer
Lines that are disconnected from each other are channeled through the top-level pressure-sensitive layer of the port
The output value of the resistor varies with the pressure.
