Optek’s Family of UV LEDs Provide Uniform Optical Light Patterns in Enviornmentally Friendly Packages

Friday, February 20th, 2009

CARROLLTON, TX (February 16, 2009) — Providing design engineers with devices capable of uniform optical light patterns over an extended temperature range, TT electronics OPTEK Technology has developed a family of ultraviolet LEDs in the UV-A spectrum. Designated the OUE8A Series, the UV LEDs are offered in a variety of wavelengths and housed in hermetic TO-46 metal can packages.  “The OUE8A Series UV LEDs eliminate any environmental concerns associated with the disposal of traditional mercury UV lamps,” said Alan Bennett, vice president of sales for OPTEK Technology. “Not only do these devices allow customers to target specific applications with the narrow wavelength emission, but they are able to do so while eliminating any mercury hazard.” The UV LEDs are ideal for medical and industrial applications including phototherapy treatment, dental applications, fluorescence and ultraviolet-visible spectroscopy; photo-catalyst curing of inks, coatings and adhesives; as well as paper currency and document validation.


Additional applications for the OUE8A Series UV LEDs include aircraft coatings and biohazard detection equipment/systems, skin dermatology, forensics, and automotive oil, A/C, and fluid detection.

The OUE8A Series UV LED family includes:

• OUE8A380Y1 – peak wavelength ranges from 375nm to 380 nm, with an optical power output range of 1.8mW to 8.1mW

• OUE8A385Y1 – peak wavelength ranges from 380nm to 385nm, with an optical power output of 1.8mW to 8.1mW

• OUE8A390Y1 – peak wavelength ranges from 385nm to 390nm, with an optical power output of 1.8mW to 8.1mW

• OUE8A395Y1 – peak wavelength ranges from 390nm to 395nm, with an optical power output of 3.1mW to 9.8mW

• OUE8A400Y1 – peak wavelength ranges from 395nm to 400nm, with an optical power output of 5.8mW to 13.4mW

• OUE8A405Y1 – peak wavelength ranges from 400nm to 405nm, with an optical power output of 5.8mW to 13.4mW

• OUE8A410Y1 – peak wavelength ranges from 405nm to 410nm, with an optical power output of 5.8mW to 13.4mW

• OUE8A415Y1 – peak wavelength ranges from 410nm to 415nm, with an optical power output of 7.3mW to 15.4mW

• OUE8A420Y1 – peak wavelength ranges from 415nm to 420nm, with an optical power output of 7.3mW to 15.4mW

• OUE8A425Y1 – peak wavelength ranges from 420nm to 425nm, with an optical power output of 7.3mW to 15.4mW


All of OPTEK’s UV LED devices have an 18º typical half power emission angle and a pulsed forward current of 1.6A. Operating temperature ranges from -40ºC to +85ºC. The OUE8A Series UV LEDs are RoHS compliant and ESD protected for reliable operation


EAO’s Rugged Keypad Solutions Offer Seamless Integration Offered Through Marsh Electronics

Wednesday, February 18th, 2009

EAO, a leader in vandal-resistant keypad and keyboard technology, specializes in building fully-customized, illuminated keypad solutions which are ready to integrate within any application. Using the S.series keypad that is constructed from ultra-tough Zamac, EAO can design a stylish and distinctive keypad solution tailor-made for applications within demanding and harsh environments. These keypads are well suited for security and access control applications, particularly within unsupervised areas. EAO’s standard products within the S.series range include 12 or 16 key keypads with a choice of telephone or hexadecimal II configurations. There are extensive possibilities for customization including ‘halo’ illumination.  This style presents the illumination around the character on each key in a range or combination of colors. A library of more than 20 different illuminated key characters are available as part of EAO’s standard offering. EAO also includes a character-design service if special markings are required as well as laser engraving facilities for non-illuminated keypads (subject to minimum order quantities). EAO’s innovative approach to individual projects makes use of flexible in-house development and manufacturing technologies. They will advise on issues such as environmental protection, mounting, cable and termination, end user-friendliness and tactile feel to ensure the best solution for each customer. S.series keypads offer superior performance and high-tactile feedback to provide a reassuring feel for the user. Sealed to IP67 standards against water, dust, and with their resistant to heat, shock and vibration, these units require minimal maintenance.  Therefore, they deliver excellent value in terms of lifecycle-cost benefits. EAO’s S.series is tested for lifetime quality of up to 4 million operations, certified according to the latest international standards, and is RoHS compliant.  eaokeypad.jpg
