Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.

Toshiba Lighting Technology has released LED lighting units of the same size and brightness as the 30mm circular fluorescent lamps. It will be launched on December 25, 2012 together with special lighting fixtures. New products cannot be used directly on existing fluorescent lighting fixtures.
Toshiba Lighting Technology began selling the LED lighting unit "LED Unit Flat Series" from October 2009. The new product is equivalent to the "1700 Series" of the LED lighting unit. The LED lighting unit uses a GX53 base with a thin structure. By combining the company's self-developed heat dissipation technology and power miniaturization technology, the LED's unique thin and compact shape is realized. The light source can be replaced freely like a light bulb. Therefore, after installing the lighting fixture, the color of the light can be changed without changing the lighting fixture depending on the application and environment.
The new 1700 series has an outer diameter of 205mm and a diameter of 30mm. It is basically the same size as a circular fluorescent lamp with a diameter of 30mm. In terms of brightness, the white color is 1700 lumens, the bulb color is 1530 lumens, and the brightness is the same as the circular fluorescent lamp with a diameter of 30 mm (Toshiba white FCL30N/28 is 1600 lumens).
In order to realize a light-emitting method that can replace the circular fluorescent lamp, the LEDs are arranged in a ring shape, and the lens cover is used to control the light distribution. The new product consumes 21.3W of power, which is about 33% less than the 32W of a circular fluorescent lighting fixture with a 30mm diameter. In addition, the rated life is about 40,000 hours that is about 6 times that of the fluorescent lamp of 6000 hours. The new products are available in both twilight and bulb lights. The suggested retail price is 12,600 yen (including tax, the same below).
The new product cannot be used directly on a 30mm diameter circular fluorescent lamp on an existing lighting fixture. Therefore, Toshiba Lighting Technology will simultaneously launch three special lighting fixtures for small ceiling lamps used in apartment common areas and residential gates. A product will be launched for indoor use on December 25, 2012 (suggested retail price is 6,300 yen), indoor use on January 15, 2013 (suggested retail price is 7,350 yen) and outdoor use (recommended) The retail price is 9765 yen). The company plans to expand the product line of special lighting equipment in the future.
