Changeover Dry Reed Switches Now Available from Coto Technology Coto Technology has introduced the RI-90 Series changeover dry reed switch. With an initial contact resistance of 140 milliohms (max), the switch is ideal for high-reliability applications in Automatic Test Equipment, Security, Industrial and Consumer Applications. Additionally, the RI-90's Form C contact configuration offers more options for reed switch sensors applications. Coto's RI-90 Series, with a 15mm max glass length, is a single-pole, double-throw (SPDT) type, having three contacts: a common contact, a normally-open contact and a normally-closed contact. When brought in the proximity of a magnetic field, the common contact will first open with the normally-closed contact (NC), and then make contact with the normally-open (NO) contact as long as the magnetic field is applied. The RI-90 Series Ruthenium contact layers provide long-life switching at a wide variety of loads. The maximum switching current is 400 mA and 125VAC or 175VDC switching voltage. New BGA Reed Relays Provide Superior RF Performance Coto Technology, of Providence, RI, has announced the release of two patented ball-grid-array (BGA) Reed Relays. The B10 and B40 BGA relays utilize breakthrough patented technology to provide leadless relay designs with enhanced RF performance. The signal path in the BGA between input and output is designed as an RF transmission line, with an RF impedance close to 50 ohms throughout the relay. With either B10 or B40 BGA relays, the designer is able to switch or pass signals with wider bandwidth and faster rise time than alternate technologies. This is particularly important for Mixed Signal IC testers. BGA packaging allows relays to be easily integrated on boards designed for surface mount processing. The B10 is a single channel Form A BGA that uses a minimum board space of only 0.1 sq in. 3.3V or 5V coils are standard and the RF insertion loss (–3dB roll-off point) is >10 GHz. Single channel simplicity makes B10 an economical choice for RF switching, with prices < $10.00 at 1K. Delivery: stock to six weeks. The B40 is a BGA with four independent form A channels in one quad package requiring only 0.215 square inches of board space. Both 3.3V and 5V coils are available and the RF insertion loss (–3dB roll-off point) is >11 GHz. Interchannel RF crosstalk is minimized by a combination of coaxial and magnetic shielding. Adjacent channel RF crosstalk is –25dB @ 11 GHz. Ultra-Miniature Surface Mount Reed Switches Coto Technology, of Providence, RI, a leading global supplier of high-quality reed switches and relays, has introduced three new additions to its growing line of surface mount Reed Switches. These ultra-miniature SMT switches, with 5 mm max glass length, feature a wider flat lead design to provide both stability during component placement and improved solderability for surface mounted applications. The RI-80SMD is Coto's newest and smallest SMT switch; it is available in three different Gull or "J" lead configurations. The J leaded version with .279" (7.1 mm) is the smallest SMT reed switch sensor available in the industry today. The RI-80SMD is rated at 5W, packaged in Tape & Reel to further facilitate automated processing. Ultra-Miniature Surface Mount Reed Relays Coto Technology offers the 9852 series as the smallest Form "C" SMD reed relay available, with a footprint of 0.078 sq. in. Expected life is 200 million cycles (N/O contact), and 100 million (N/C) at 1V 10mA load. RF bandpass (-3dB) is 4GHz (N/O) or 3GHz (N/C). Isolation and return losses at 1 GHz are –10dB and –20dB respectively. An external magnetic shield reduces electromagnetic interaction between closely spaced relays. This combination of small size, long life and good RF bandpass is unattainable by electromechanical or micromachined relays. Gull-wing, "J"-lead or axial surface-mount styles are available in tubes or tape-and-reel spools. New Reed Relay & Reed Switch Catalog Coto Technology, of Providence, RI, has unveiled its newest full-line product catalog featuring reed relays, sensors, and dry reed switches. The 144-page catalog includes detailed product information, electrical specifications and mechanical drawings for Coto's full product line – including Coto's many new product series and configurations. The catalog also provides newly expanded technical applications sections, color performance graphs, packaging and pad layout recommendations, product selection guides and quick reference charts to facilitate product specification. In addition to print, the catalog is available in .pdf format for download, as well as for viewing on Coto's website. Miniature Proximity Sensors for SMD Mounting Coto Technology, of Providence, RI, a leading global supplier of high-quality reed switches and relays, has introduced two new additions to its growing line of Molded Reed Switch sensors. These miniature sensors, which are molded in thermoset plastic to provide greater protection, have proven to be ideal choices for automated pick-and-place applications. The CT05 is Coto's newest and smallest molded switch with a body length of only 0.252" (6.4mm). Based on Coto's 5mm switch design, it is available in Gull or "J" lead configurations and is the smallest molded reed switch sensor available in the industry today. The CT05 is rated at 5W and offers the same rugged design features of the CT10, but at a smaller size. The popular CT10 model has now been made available with a G4 lead configuration, which features a wider flat lead to provide both stability during component placement and improved solderability for surface mounted applications. The CT10 is rated at 10W. Both products are packaged in Tape & Reel to further facilitate automated processing. World's Smallest Reed Switch Now Measures 5mm Max Coto Technology, of Providence, RI, a leading global supplier of high-quality reed switches and relays, has successfully developed and is now marketing the smallest reed switch available in the industry. Coto's RI-80 , with the "ultra-small" size of 5mm, (max glass length) is ideal for size-restricted sensor applications in Medical Electronics such as pacemakers, endoscopes, and hearing aids as well as miniature industrial position sensors and consumer applications – including Laptops, PDA's, mobile phones and battery operated applications where no external power supply is available. And, because it is rated at 5 watts, the RI-80 is also well suited for high-reliability, small signal automatic test equipment. Coto Technology's RI-80 is the only true 5.0mm reed switch available on the market - while competitive products are promoted as being as 5mm in length, in actuality, they measure 5.4-5.6mm. Coto's RI-80, 5mm reed switch is priced according to configuration and quantity, with typical 4 to 8 week delivery.
