RI-46A

RI-46 Series RI-46 SERIES Micro dry-reed switch hermetically sealed in a gas-filled glass envelope. Single-pole, single-throw (SPST) type, having normally open contacts, and containing two magnetically actuated reeds. The switch is of the double-ended type and may be actuated by an electromagnet, a permanent magnet or a combination of both. The device is intended for use in relays, sensors, pulse counters or similar devices. EATURES RI-46 SERIES FEATURES u Can switch main voltage u Can handle up to 40 W load u Contact layers: Gold, sputtered ruthenium u Superior glass-to-metal seal and blade alignment u Excellent life expectancy and reliability F OR A LL MODELS R I-46 G ENERAL DATA FOR ALL MODELS RI-46 Dimensions in inches (mm) AT-Customization / Preformed Leads Besides the standard models, customized products can also be supplied offering the following options: ! Operate and release ranges to customer specification ! Cropped and/or preformed leads C OILS All characteristics are measured using the Philips Standard Coil. For definitions of the Philips Standard Coil and the standard MIL Coil, refer to “Application Notes” in the Reed Switch Technical & Application Information Section of this catalog. Standard Relationship between Relationship betw een Philips Standard Coil and Standard dard MIL Coil Operate value of standard MIL Coil = 0.79 x operate value of Philips Standard Coil + 2.26 AT.

MECHANICAL DATA Contact arrangement is normally open; lead finish is tinned; net mass is approximately 0.28 g; and can be mounted in any position. S HOCK The switches are tested in accordance with “IEC 68-2-27”, test Ea (peak acceleration 500 G, half sinewave; duration 11 ms). Such a shock will not cause an open switch (no magnetic field present) to close, nor a switch kept closed by an 80 AT coil to open. IBRATION V IBRATION The switches are tested in accordance with “IEC 68-2-6”, test Fc (acceleration 10 G; below cross-over frequency 57 to 62 Hz; amplitude 0.75 mm; frequency range 10 to 2000 Hz, duration 90 minutes). Such a vibration will not cause an open switch (no magnetic field present) to close, nor a switch kept closed by an 80 AT coil to open. PERATING A ND ORAGE EMPERATURE O PERATING AND STORAGE T EMPERATURE Operating ambient temperature; min: -55°C; max: +125°C. Storage temperature; min: -55°C; max: +125°C. Note: Temperature excursions up to 150°C may be permissible. For more information contact your nearest Coto Technology sales office. S OLDERING The switch can withstand soldering heat in accordance with “IEC 68-2-20”, test Tb, method 1B: solder bath at 350 ±10°C for 3.5 ±0.5 s. Solderability is tested in accordance with “IEC 68-2-20”, test Ta, method 3: solder globule temperature 235°C; ageing 1b: 4 hours steam. W ELDING The leads can be welded. MOUNTING The leads should not be bent closer than 1 mm to the glassto-metal seals. Stress on the seals should be avoided. Care must be taken to prevent stray magnetic fields from influencing the operating and measuring conditions. MECHANICAL STRENGTH The robustness of the terminations is tested in accordance with “IEC 68-2-21”, test Ua1 (load 40 N).
