EMC electromagnetic wave absorber 'DuraSorb DSH-600H'

Dual pyramid design! Introduction of non-hygroscopic and flame-retardant EMC wave absorbers!

The "DuraSorb DSH-600H" is an EMC wave absorber that provides a smooth transition from free space impedance to lossy ferrite tile bases. As a result of its optimal design, it guarantees high performance in both low-frequency and high-frequency ranges exceeding 1 GHz. It has reflection characteristics of over 17 dB from 60 MHz to 3 GHz and over 20 dB above 4 GHz. Due to its independent bubble design, it is inherently non-hygroscopic and designed to have outstanding flame retardancy. 【Features】 ■ Frequency range: 30 MHz - 40 GHz ■ Compliant with MIL-STD-461, ANSI C63.4, CISPR 16, and CISPR 25 standards ■ Robust structure and design considering precise installation ■ Non-hygroscopic and flame retardant *For more details, please refer to the PDF document or feel free to contact us.

Radio Wave Absorber "E&C FHY-NRL"

Flat hybrid electromagnetic wave absorber

E&C FHY is a thin, flat, multi-layer hybrid absorber developed for EMC anechoic chambers. It consists of a lightweight matching layer and a flat protective top plate. This design allows it to be used on top of ferrite, providing sufficient performance for EMC anechoic chambers in the frequency range from around 30 MHz to 2 GHz. For applications requiring wideband performance from around 30 MHz to over 30 GHz, the optimal absorbers are E&C VHY or E&C HX, which can be selected based on the available space. 【Specifications】 ○ Frequency range: 30 MHz to 2 GHz ○ Absorption characteristics: up to -40 dB For more details, please contact us or download the catalog.

Radio wave absorber IT foam directional radio wave absorber Wi-Fi countermeasures

It is an electromagnetic wave absorber made of olefin-based resin foam, which exhibits excellent effects in suppressing wideband characteristics, is easy to cut and install on-site, and reduces multipath.

- It is capable of wideband radio wave absorption from 300 MHz to 110 GHz and excels in radio wave absorption performance for oblique incidence. It is easy to cut and process, making installation at the site straightforward. - It is an electromagnetic wave control material and radio wave absorber effective for wireless technology, EMC, and noise countermeasures. - Made primarily from polyolefin-based resin and carbon, it can be produced in suitable thicknesses depending on the applicable frequency. - Wireless LAN access points stored in the ceiling can cause interference due to reflected waves from the deck plate within the ceiling, so the radio wave absorption box cuts off upward radio waves, enhances the directionality of downward waves, and absorbs excess radio waves. - Installing it on adjacent partition walls in the same floor tenant prevents radio wave interference and secures channels. - Near glass windows, it prevents radio wave leakage to the outside and, when used in conjunction with shielding films and floor SS sheets, reduces radio wave interference between floors and inside and outside. - The box for wireless LAN access points, when combined with SS sheets, prevents radio wave interference. - It is used as an electromagnetic wave control material for adjusting wireless LAN access point equipment during system installation (used to isolate and adjust several units at hand).
