FSS1500NGR Datasheet | Honeywell

DESCRIPTION Honeywell’s FSS-SMT Series force sensors are designed to be one of the most reliable force sensors available as illustrated by 20 million Mean Cycles To Failure (MCTF) at 25 °C [77 °F] rating. This low profile Surface Mount Technology (SMT) sensor allows for automated assembly on a printed circuit board, often helping the customer to reduce assembly costs. The FSS-SMT Series force sensor is designed to provide precise and reliable force sensing performance in a pact mercial-grade package. The sensor incorporates Honeywell sensing technology that uses a specialized piezoresistive micromachined silicon sensing element. The low power, unamplified, unpensated Wheatstone bridge circuit design provides inherently stable millivolt output over the force range. Force sensors operate on the principle that the resistance of silicon-implanted piezoresistors will change when the resistors flex under applied force. The sensor concentrates force from the applications, 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 m V output level change. The sensor package design incorporates patented modular construction. The use of innovative elastomeric technology and engineered molded plastics results in load excitation capacities of 44 N over-force. The stainless steel ball provides excellent mechanical stability, and is suitable for a variety of potential medical and mercial applications. FEATURES /BENEFITS - Surface Mount Technology allows for automated assembly and may eliminate hand soldering - Ro HS-pliant materials meet Directive 2002/95/EC - Low deflection (30 microns typical at full scale) help reduce measurement error - Direct mechanical coupling of the actuation ball to the sense element reduces coupling errors and keeps mechanical hysteresis to a minimum - Product rating of 20 million MCTF at 25 °C...
