reed relay application


Warum das so sein kann, ist leicht erklärt. Reed relays use the reed switch as the heart of their switching mechanism. Figure 1 This ATE board, fully loaded with newly designed miniature reed relays, shows that this classic component still has a vital role in the latest generation of ATE systems. 0000035947 00000 n Non-standard package sizes and pinouts, custom coil and shielding designs, and multi-pole configurations are common variables. 0 Sealed in a long, narrow glass tube, the contacts are protected from corrosion. The small size and high-speed of the reed relay make it a great choice for many switching applications. Sie können jetzt ausgewählte Produkte direkt auf TE.com kaufen. The reed switch may be latched in its normally open state or its normally closed state. The operate time specification is determined by the rate of rise of the magnetic field which determined by the coil inductance and then the inertia of the reed switch blades due to their mass and compliance. Pickering Reed Relays for high voltage applications can stand-off from 1kV to 15kV and switching 500V to 12.5kV at up to 50W. Because the contacts in a Reed Relay are hermetically sealed, the contacts can switch low level signals as low as femtoamps and nanovolts. These are available with Tungsten or Rhodium contacts, depending on the switching requirements of the applications. Application Notes - Reed Relays 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. Die Relais sind zu 100 % auf dynamischen Seite 3 von 4. The activating magnetic field is applied via an external electromagnet or even a permanent magnet (for this reason, reed relays are often used to detect door/window closures). 0000004281 00000 n Its state depends upon the.

Some, such as PIN diodes, are designed for RF applications, but the most commonly found devices that compete with reed relays are based on FET switches. Yes, solid-state relays (SSRs, also called optocouplers) have taken over many of their traditional roles, but old-style relays still solve some nasty design problems with no headache, hassle, or surprises. Pickering Reed Relays for high voltage applications can stand-off from 1kV to 15kV and switching 500V to 12.5kV at up to 50W. Sources: Electronics Notes, Wikipedia. RELAY APPLICATIONS Reducing Magnetic Interaction in Reed Relay Applications Reed Relays are susceptible to magnetic effects which may degrade performance under certain conditions. <]>> Da kann so ein einfaches Bauteil schon mal ignoriert werden. 0000004666 00000 n 8 standexmeder .com Reed Switch Characteristics Fig. Back to top. 0000001821 00000 n zu arbeiten oder eine Software stabil zu machen.

Regional Scope: North America, Europe, Asia Pacific, Latin America, Middle East and Africa: Customization scope: Free report customization (equivalent up to 8 analysts working days) with purchase. A latching reed relay uses a Form A switch magnetically biased by permanent magnet as well as latching and unlatching coils. The input signal may be heat, light, electricity and magnetism. Reed relays are thus not ideal for extremely low-voltage applications as their thermal EMF may introduce enough noise to cause errors in your measurements. This report presents a practical approach to reducing magnetic effects among and between Reed Relays. 0000240740 00000 n GÜNTHER® High Voltage Reed Relays have outstanding performance characteristics in insulation resistance and stand-off voltage.
