ASAP Semiconductor LLC
Relays Relays are a commonplace component within countless systems and applications, serving as an electrically operated switch. With the use of input terminal sets and operating contact terminals, a relay may be used for the management of a single control signal or multiple. With their control of signals and their operational characteristics, relays also may convert smaller electrical inputs into larger outputs, increasing their uses and abilities. Capable of being either a switch or an amplifier... (read more) -
S. Himmelstein & Company
OVERLOAD/OVERRANGE - WHAT’S THE DIFFERENCE? Two easily overlooked, yet extremely critical parameters when evaluating and specifying torque transducers are - Mechanical Overload Rating and Electrical Overrange. Each is important, but often confused and misunderstood. Overload - represents a mechanical safety factor for the sensor element. Normally expressed as a percentage of the sensor full scale rating, it is the maximum load limit of the sensor before yield or physical deformation. S Himmelstein and Company products are available... (read more) -
