Use magnetic simulation software to gain a thorough understanding of a sensor's magnetic operating environment under a wide range of conditions. This tool characterizes sensor performance while operating and interacting with magnetic fields in motion. It should consider any ferrous metals located near the sensor and magnetic actuator assembly that could shunt the intended magnetic field away from the sensor. This simulation should be done prior to investing significant time in benchtop testing and tooling. Consider the temperature of the application since it has the most impact on the magnetic material. Some magnetic materials such as neodymium have limitations on the maximum allowable operating temperature. Once the maximum temperature has been exceeded, the flux density significantly decreases and cannot be reversed. For benign environments such as indoor applications, a...
