Nd-Fe-B Neodymium Magnet Rare earth magnets can be classified into a samarium-cobalt magnet and a neodymium magnet. A characteristic of a samarium-cobalt magnet is strong magnetic force. Its merit is that it is resistant to rust and high temperature, but it tends to be easily broken. It is popular as the most suitable material for a small and lightweight magnet, like neodymium. A neodymium magnet can produce the strongest magnetic field in the world among those sold in the current market. The shape of a neodymium magnet can be round, square or ring according to what it is used for. Although it is mechanically strong, its surface is processed since it is easily rusted and therefore it must be used below 80°C.

Straightness Measuring Instruments Straightness Tester, repeat meters, and roll calipers.

Straightness Tester
On the granite standard straight edge lower surface, 3 saddle supports are attached.
The accuracy surface is high precision and light weight.
By moving the slider, straightness can easily be measured.
By performing Zero setting on the master surface plate, it is possible to measure the work absolute value
Rather than a dial gauge, by using a proble with external output, it is possible to perform data processing.

Repeat Meters
Measurement of Surface Plate Flatness, Straightness etc can be done easily.
At 3 points o fthe fulcrum interval 100mm, flat surface unevenness is measured
Before measurement, perform zero setting on the master surface plate.

Roll Caliper
For measuring large rolls.
It is lightweight because light alloy metal is used as the material. (However, the frame is made of Cast Iron )
4 pcs of job run roller have bearings in them and they are precision grinded.
Movement on the roll is slow and smooth.
A special interval graduation is inprinted on the arm. By matching a bracket onto the work measurement figures, it is possible to easily set a Dial Gauge on the roll center of the work.
A 0.01mm graduation dial gauge is supplied with the product.

　・The storage box is designed in such a way that the main body will have to be disassembled before putting it into the box.

LED Lamps
Model:
Description: SEIWA Electric Mfg. Co., Ltd. has long been involved in the Research and development of LED lamps to meet the need for high performance information display systems and indicator lamps, fully utilizing know-how accumulated through the manufacture of various information display systems and industrial lighting equipment delivered to many customers.
Recently, by the use of various unique manufacturing techniques. We have succeeded in the mass production of blue LED's, which was considered difficult. SEIWA's LED's are characterized by an original electrode arrangement, which assures a uniform luminous intensity distribution and low operating voltage. These LED's have a transparent electrode structure, which contributes to optical output improvement. In addition, we have developed a chip sorter, which sorts out chips according to wavelength and brightness with high accuracy. The chip sorter permits a stable supply of high quality LED chips.
