Universal Serial Bus (USB)

 

Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The Universal service bus design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps.

Products & Services
Video Cameras
Video cameras record live-action scenes that are available for viewing via a stored or transmitted video feed. This allows the user to create a permanent and detailed chronicle of events. Video cameras record dozens of pictures (or frames) a second that when viewed in succession, clearly distinguish the translation of an object or person over time.
Motion Controllers
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
DC Motor Drives
DC motor drives act as the interface and power supply between a motion controller and a DC motor.
AC Motor Drives
AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.
Stepper Motor Drives
Stepper motor drives power unipolar and bipolar stepper motors in full step, half step, and microstep motion control applications.
