FSS Series force sensor, uncompensated/unamplified, low profile SMT package, 0 N to 15 N force range, standard tube packaging.

The FSS Series Force Sensor provides precise, reliable force sensing performance in a compact, commercial-grade package at a cost effective price. The sensor features a proven sensing technology that uses a specialized piezoresistive, micromachined silicon sensing element. The low power, unamplified, uncompensated Wheatstone bridge circuit design provides inherently stable mV outputs over the force range.

Force sensors operate on the principle that the resistance of silicon-implanted piezoresistors will increase when the resistors flex under any applied force. The sensor concentrates force from the application, through the stainless steel ball, directly to the silicon-sensing element. The amount of resistance changes in proportion to the amount of force being applied. This change in circuit resistance results in a corresponding mV output level change.

The sensor package design incorporates patented modular construction. The use of innovative elastomeric technology and engineered molded plastics results in overforce capacities of up to three times the rated force. The stainless steel ball provides excellent mechanical stability and is adaptable to a variety of applications.

The FSS Series Sensor delivered 20 million operations in Mean Cycles to Failure (MCTF) reliability testing at 50°C [122°F]. This test determines the number of possible sensor operations at full scale until failure.
