The RM2100 is comprised of two Sen-XY-f sensor coils, pn 13104, and a MagI2C ASIC controller, pn 13156, which forms the basis for a 2-axis digital compass. The RM3100 is the same as the RM2100 but adds a Sen-Z-f sensor coil, pn 13101, such that compassing measurements are not constricted to the horizontal plane

+REED RELAY - A reed relay is an electromagnetic switch that uses a magnetic field to control a reed switch. It consists of a coil wrapped around a hermetically sealed glass capsule containing two ferromagnetic reeds. When the coil is energized, it creates a magnetic field that pulls the reeds together, closing the circuit, while a spring force separates them when the coil is de-energized. Reed relays are known for their speed, long life, and ability to switch low-level signals with high reliability.
