LITHIUM-ION BATTERY CHARGERS

Dual input

The LTC4076 and LTC4077 standalone dual-input linear battery chargers charge single-cell Lithium-Ion batteries from wall adapter or USB power sources. They use a constant-current/constant-voltage algorithm for charging, with charge current programmable up to 950 mA from a wall adapter supply, or programmable up to 650 mA from a USB supply while automatically sensing the presence of voltage at each input. They are offered in a low profile 10-lead 3×3 mm DFN package. Linear Technology Corp.http://rbi.ims.ca/4398-606

KEYBOARD AND MOUSE

Sealed

The InduProof2™ keyboard and InduMouse™ is designed for medical and food industry applications. They are encased in a silicone cover that is highly resistant against chemicals. The able connections consist of non-spiral, smooth and sealed data cables. They use mechanical keyswitches for enhanced tactile feel and durability. Both are ideally suited for hygiene-sensitive hospital and laboratory environments, and can also be used in food processing applications that require a high degree of chemical resistance for equipment disinfection.

ROTARY SENSORS

12-bit resolution

The RSC3700 family of non-contacting rotary sensors is engineered to provide 360-degree absolute angle measurements with 12-bit resolution. Measurements are referred to a mechanical index point, providing retention of position in the event of a power failure. A microprocessor incorporated into the sensor allows a custom output characteristic curve to be preprogrammed for a specific application. It has a resolution of ± 0.09 degrees.

STEP-UP CONVERTER

PWM dimming

The LT3486 is a dual step-up dc/dc converter that is engineered to drive up to 16 white LEDs (8 LEDs in a series per channel) with constant current. True PWM dimming delivers constant current to the LEDs, keeping the emitted light a constant color. Dimming is controlled with the duty cycle of the PWM driver, enabling a wide 1,000:1 range. It features an input voltage range of 2.5 to 24V. Linear Technology Corp.http://rbi.ims.ca/4398-609

PHOTOELECTRIC SENSORS

Miniature package

The BOS 2K family of photoelectric sensors are designed to combine full functionality in a miniature package that is 20×7.5×10 mm in size. They have a scan range of up to 1.2m and supply four different sensing modes. A variety of reflectors, mounting brackets, and connectors is available. They are ideal for a range of assembly and handling applications. Balluffhttp://rbi.ims.ca/4397-610
