Alternatively relays may be warmed prior to soldering. RF Reed Relays. Dry reed relays are made of coils wrapped around reed switches. Cynergy3 recommend the following wave flow soldering profile: 250oC ±10oC, immersion time 3 seconds. Verification of any particular voltage or frequency combination, within the HF band (1–30MHz), can be undertaken upon request. Cynergy3's range of RF reed relays are carefully designed to provide minimal RF signal loss and low contact resistance. The switching power, when quoted, will be for a resistive load. Figure 3: Mounting Configurations to Minimise Magnetic Interference (Note Orientation). The normally closed (Form B) reed relay was designed for just such a situation. By definition, Electrical Relay is a switching device that can be used to open or close the contacts electrically. MERCURY WETTED CONTACT: A form of reed switch in which the reeds and contacts are wetted by a film of Mercury obtained by a capillary action from a Mercury pool encapsulated within the reed switch. A rigorous reliability testing program is therefore a vital tool for providing our customers with technical support, and also for continuously improving the quality of Coto’s products . Reed relays can be supplied with changeover switches – the reed switch has a normally closed contact (when no magnetic field is applied) and a normally open contact (which closes when the field is applied). Reed relay specifications are different to those of other components normally found in electronic circuits. For such applications we have relays built with high insulation resistance reed switches. Cynergy3 relays are not hermetically sealed (unless stated otherwise) and as such are not suitable to aqueous cleaning solutions or processes. Some of them are latching relays, reed relays, power relays, thermal relays and high voltage relays. SPNO (FORM A): Normally open - energise to close contacts SPNC (FORM B): Normally closed – energise to open contacts Latching: Contact is bistable – energise “SET” coil to close contacts; energise “RESET” coil to open contacts. what is reliability? In reed relays, current applied to this winding generates a magnetic field which operates the reed switch . Reed Relay; Reed Relays consist a set of magnetic strips which is closed within a glass tube. Various types of relays are used in various applications based on different criteria such as rating of contacts, number & type of contacts, the voltage rating of contacts, operating lifetime, coil voltage & current, package, and so on. In general breakdown across the contacts occurs at a higher RF peak voltage than DC. COIL: An assembly consisting of one or more turns of wire around a common form . Garden Grove 92841, CA The two may be considered directly equivalent, at mains frequency (i.e. Also the internal construction of the relay, including complete epoxy encapsulation, results in reed relays with insulation resistances of 1x10E+12 Ohm or greater, between mutually isolated terminals. The reed switch is composed of two overlapping ferromagnetic blades (called reeds) hermetically sealed within a glass capsule that is filled with an inert gas. Coto Technology, Inc. originated in Providence, Rhode Island, USA in 1917 as Coto Coil Incorporated – a company specializing in the design and manufacture of coil windings. The following guidelines should therefore be followed when adopting assembly, soldering and cleaning processes. Reed relays have also found numerous applications in RF and microwaveswitching applications. This reed operates as both an armature and a contact blade.The magnetic field applied to the coil is folded around this tube that makes these reeds motion so that switching work is acts. to minimize magnetic coupling between the relay and external magnetic fields. Operate and release times for the relays are quoted with coil suppression fitted (unless otherwise stated). Please contact sales for further information on the suitability of various cleaning solutions. Registered address: 7 Cobham Road, Ferndown Industrial Estate, Wimborne, Dorset, BH21 7PE, United Kingdom. It has a biasing magnet so in the closed position, the relay coil draws no power. Ferromagnetic screening can be used to contain this magnetic field, so allowing closer placement of reed relays on a PCB. Rhodium offers superior low contact resistance, which, coupled with Cynergy3's copper plated reed switch technology, enables Cynergy3 to produce very low loss RF reed relays, with exceptional current carry performance. With Sanyu Electric, Nucletron represents the technology leader in the reed relay market. When the coil is energized, the two reeds are drawn together such that their contacts complete a path through the … Maximum exposure time 10 seconds. It should be noted that relays, used in a power switching application, will experience reduced operating life; it is recommended that sales be contacted for advice on specific applications. Used to simulate the outer conductor of a coaxial cable for high frequency transmission . reed relay applications. Mercury-wetted relay • A mercury-wetted relay is a form of reed relay in which the contacts are wetted with mercury. Tungsten contacts are used exclusively for our high voltage 'D' series range, where they are offered as high voltage switching contact able to switch voltages up to 10kV DC or AC peak at very low current. 50 or 60Hz). Because the contacts in a Reed Relay are hermetically sealed, the contacts can switch low level signals as low as femtoamps and nanovolts. Reed Relay Market Size by Applications: Security Systems Telecom Equipment Process Control Systems Automatic Test Equipment Electronic Instrumentation . The 9006 Series is a general-purpose economy potted version of the 9001 for applications with less stringent requirements. RRE Home » Reed Switch and Reed Sensor Applications » Types of Applications » Electromagnetic or Relay Type Reed Relay in Food Processor Application When it is necessary to control a circuit load by using a separate low-power signal, or where the states of several circuits must be controlled by a single signal, such types of Reed Switch applications can be classified are Relay Applications.

We doesn't provide reed relay applications products or service, please contact them directly and verify their companies info carefully. Relays useful for applications where conservation of current is required. United Kingdom, Cynergy3 Components LLC Figure 4: Recommended Mounting for "S" and "D" Series High Voltage Reed Relays. The principal function of a high voltage reed relay is to isolate as high a voltage as possible, Cynergy3 achieve this through the use of evacuated reed switches. switch to coil or screen), caused by surface tracking, can occur more readily at high frequency than at DC. Fully screened relays offer the ultimate in low loss performance, resulting in the lowest ESR figures, significantly reducing the effects of RF coil heating, and maximising current carry performance at elevated temperatures and frequencies. We offer a wide array of reliable and cost-effective products from standard solutions to custom designs. A magnetic field is produced, when power is applied to the coil of a reed relay. As a result, these are useful for battery powered equipment. Note that the 'D' Series has magnetic screening fitted as standard. 9006 Series Potted SIP Reed Relays. important issue when deciding if a reed relay is the best application choice . The reed relays’s mechanical lifetime is also much higher than an electromechanical relay. The switch in this type of relay must be mounted vertically These relays are intended for use in DC or AC (50Hz to 60Hz) applications. Portable Defibrillators - Reed Relay application describes how our reed relay series meet high voltage demands of portable defibrillators with low power consumption Wimborne Dorset BH21 7PE Very sensitive reed relays with high coil resistance. Reed relays are a an excellent choice for lower power switching applications because of their long life and fast operation. Cynergy3's reed relays are high performance products and the materials and methods of construction are significant factors in achieving performance specifications. Partially screened relays will offer extended current carry capability at elevated temperatures and frequencies up to 30MHz, over unscreened variants, due to lower ESR. The input signal may be heat, light, electricity and magnetism. They are ideal for such applications as transformer or cable testing or any other automatic test equipment where high voltages are involved. United States, © 2019 Sensata Technologies, Inc. All Rights Reserved. The Series 104 is a range of Single-In-Line reed relays intended for voltages that are beyond the capabilities of conventional SIL reed relays.
