B&B Electronics' industrial-grade USB port protectors now include the small-form-factor, USBSSP2 “USB Sentinel” USB 3.0 surge suppressor. Unlike typical non-portable or “pass-through-panel” USB surge protection devices, B&B Electronics’ USB Sentinel is compact (4.5 x 1.22 x 0.96 inches, 11.4 x 3.1 x 2.5 cm) and portable, connecting in-line between the computer and the peripheral device to protect it from the surges, spikes, and electrostatic discharge (ESD) that can occur when connecting computers to equipment in the field and factory. With a wide (0 to 80°C) operating temperature, advanced heavy industrial emissions standards and an EN61000-6-2 heavy industrial rating, the USB Sentinel is small enough to tuck into a pocket or a laptop bag, yet tough enough to stand up to repeated use in harsh environments.
The USB Sentinel is a passive device and provides fast, 20 µsec clamping of surges - up to 700V volts on the data lines and 1000V on the power lines - without interfering with normal USB 3.0 connectivity. It is also backwards compatible with USB 2.0, providing a single USB surge suppression solution.
