RI-02 Series Dry Reed Switch
RI-02 Series
Ultra-miniature dry-reed switch hermetically sealed in a gas lled envelope.
Single-pole, single-throw (SPST) type, having normally open contacts, and
containing two magnetically actuated reeds.
e switch is of the double-ended type and may be actuated by an electro-
magnet, a permanent magnet or combination of both. e device is intended
for use in senors, relays, pulse counters or similar devices.
RI-02 Series Features
Ideal for general purpose reed relays and sensors.
Contact layers: ruthenium on gold
Superior glass-to-metal seal and blade alignment
RoHS Compliant
Dimensions for RI-02 Series
All Dimension in inches (mm) nominal
General data for all models RI-02
AT-Customization / Performed Leads
Besides the standard models, customized products can also
be supplied oering the following options:
• Operate and release ranges to customer specication
• Cropped and/or performed leads
Coils
All characteristics are measured using the Philips Standard
Coil. For denitions of the Philips Standard Coil, refer to
Application Notes in the Reed Switch Technical & Applica-
tion Information Section of this catalog.
