formerly RI-80 SMDH Series Housed Dry Reed Switch RI-80 SMDH Series Ultra-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 electro - magnet, a permanent magnet or a combination of both.

RI80SMDH-XXXX-YY Shock Lead Configuration Subset: The switches are tested in accordance with IEC 68-2-27, G1 for Gull Wing version 1 test Ea (peak acceleration 150 G, half sinewave duration G2 for Gull Wing version 2 11 ms). Such a shock will not cause an open switch (no J for J-Lead version magnetic field present) to close, nor a switch kept closed by an 80 AT coil to open. AT Ranges** Vibration Series The switches are tested in accordance with IEC 68-2-6, test Fc (acceleration 10G below cross-over-frequency 57 **Customer specific AT ranges and modifications are possible. to 62 Hz amplitude 0.75 mm frequency range 10 to Please contact your local sales representative. 2000 Hz duration 90 minutes.)
