Relay, Reed, SIP, SPST, 12V dc, Diode. lamps, solenoids etc.). COIL aT: The coil ampere turns (AT) is the product of the current flowing through the coil (and therefore directly related to coil power), and the number of turns . Buy SPNO Reed Relay, 24V dc DAT72415 or other Reed Relays online from RS for next day delivery on your order plus great service and a great price from the largest electronics components Including 1 Form A (SPST N.O. In reed relays, current applied to this winding generates a magnetic field which operates the reed switch . General purpose reed relays are suitable for the construction of small switching networks, for slave switching larger relays or for operating external devices (e.g. The coil AT exceeds the switch AT Please view our large selection of reed relays below. To simplify inter-relay wiring, interconnection points are built onto the circuit board thus easing the construction of complicated wiring. Measuring only 8.6mm x 4.4 mm x 3.4 mm, the leadless design eliminates skewing of leads and co-planarity issues. Normally Closed, and SPDT varieties are also available. COTO TECHNOLOGY. Dual coils in some reed relays allow for latching capability. The UL approved reed relays have very high isolation voltages. Reed relays were developed in the 1930s at the venerable Bell Telephone Laboratories, which was looking for a small, lightweight, and extremely long-life relay for switching of telephone circuits. These relays are intended for use in DC or AC (50Hz to 60Hz) applications. Reed switches just open and close when they're near/not near a magnetic field. But when I search for reed relays I don't get results of the type that they show on Wikipedia, the ones I find are little black boxes. Reed relays consist of a coil surrounding a reed switch. Instrumentation Grade Reed Relay Product Spotlight The reed switch may be latched in its normally open state or its normally closed state. Reed Relays are available at Mouser Electronics from industry leading manufacturers. Reed Relays consist of a pair of magnetic strips (also called reed) that is sealed within a glass tube. Notification of Change of Various Reed Relay Product Packaging QuantitiesLittelfuse would like to notify you of a change relating to the product packaging quantity, Minimum Order Quantity (MOQ) and Minimum Delivery Quantity (MDQ).The purpose is to standardize and align the packaging quantity with other like reed relay products. Connect Pin 3 of the reed relay to the output pin (13) on the Arduino. Cynergy 3 DA (UL) Series Reed Relay. N° de stock RS 817-2291. The relay has 1 mV typical thermal offset voltage. Mouser is an authorized distributor for many reed relay manufacturers including COTO Technology, Magnecraft, MEDER, TE Connectivity & more. 1 A Reed Relays are available at Mouser Electronics. The reed switch is an electrical switch operated by an applied magnetic field.It was invented in 1922 by a professor at Leningrad Electrotechnical University, and later evolved at Bell Telephone Laboratories in 1936 by Walter B. Ellwood into the reed relay. * Charles Dickens, Dombey and Son There is a snaky gleam in her hard grey eye, as of anticipated rounds of buttered toast, relays of hot chops, worryings and quellings of young children, sharp snappings at poor Berry, and all the other delights of her Ogress's castle. The resistance governs the current that will flow through it when the relay is active or on. This Reed Relay is the smallest in the industry and switches in the billions of operations. A latching reed relay uses a Form A switch magnetically biased by permanent magnet as well as latching and unlatching coils. Reed relays require low coil current and are capable of fast operate and release times. Relays . Standex Electronics is the leading global reed relay expert. Some of the main specifications and parameters for reed relays are given below: Coil resistance: The coil resistance is a key parameter for any reed relay.
