Optical Switches
-
This latest technology platform presents the best value in terms of size, form factor, durability, and cost. The design of our MEMS optical switch centers on DiCon's proprietary dual-axes tilting MEMS mirror and is expandable up to a 1x36 switch configuration. Large fan-out 1xN optical switches and non-blocking fan-out/fan-in NxM matrix optical switches are built by cascading multiple of these 1xN switches. The MEMS 1xN fiber optic switch passes the stringent Telcordia GR-1221 qualification and is vastly deployed in today’s optical communication networks. With a lifetime of over a billion cycles, the durability of this MEMS device makes it a perfect choice for optical network monitoring applications that require frequent switching.

Coaxial Multi-Position Switches
-
Space-qualified multi-position switches are sometimes used during launch, which means that they need to be operational under very harsh conditions, such as continuous RF power during actuation (‘hot switching’), as well as high levels of shocks and vibrations. Dow-Key has proven designs on numerous programs such as ORION, VENICE, and AMOS.

Shaft Speed Switches
-
A speed switch senses rotating shaft speed, comparing it to one or more settable over/under/zero speed alarm trip-points. A shaft speed sensor detects magnets embedded in a shaft-mounted pulser wrap/disc. As the shaft rotates, the passing magnets are detected across an air-gap as pulses with frequency proportional to shaft RPM. When a conveyor belt or bucket elevator begins to slip the pulse frequency (shaft RPM) crosses to the alarm side of a trip-point threshold, a corresponding relay de-energizes, providing shutdown or alarm.
