Magnetic Latching Indicator
Ideal for Medical Electronics Applications

ROLLING MEADOWS, ILLINOIS, USA. L-3 Communications, Electrodynamics has introduced a new magnetic latching nonvolatile indicator designed for extremely severe environments. The CI 25 is a printed circuit board mount indicator that can survive an autoclave environment that has temperatures in excess of 132° C with 100% RH under 30 PSI. The indicator's molded rotor magnet changes position when energized with a 50 ms or longer pulse and exposes an extremely visible high contrast color even in high ambient light.

The CI 25 is a miniature single coil magnetic latching nonvolatile drum indicator, ideal for severe electronic applications where latching memory is desirable but high humidity or steam is present. The CI 25 was designed to survive multiple autoclave cycles without degradation to the magnetic characteristics, the material, or the medical-grade inks used.

When the indicator coil is energized with a pulse of 50 ms or longer, the highly visible drum changes position and latches to the magnetic core. The drum will remain magnetically latched to the core in the position last pulsed. Even if the fault signal is removed, the indicator will "remember" that a fault had occurred.

The CI 25 comes standard in 3, 6, or 12 VDC operating voltage configurations with customized voltage ranges available. Dielectric Strength is 100V rms. Operating temperature range is
-40°C to +134°C. Expect 500,000 cycles operating life.

Colors available are red, yellow, green and white standard against a black surface that provides excellent color contrast.

Samples available 2 weeks; production lead time 4-6 weeks after receipt of order.
