RI-21 Series Dry Reed Switch  
RI-21 Series  
Micro dry-reed switch hermetically sealed in a gas-filled 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 sensors, relays, pulse counters or  
similar devices.

General purpose reed switch  
High breakdown voltage  
Contact layers: gold, plated ruthenium  
Superior glass-to-metal seal and blade alignment  
Excellent life expectancy and reliability  
Dimensions in inches (mm)  
General data for all models RI-21  
AT-Customization / Preformed Leads  
End of life criteria:  
Besides the standard models, customized products can  
also be supplied offering the following options:  
! Operate and release ranges to customer  
specification  
Contact resistance > 1Ω after 2 ms  
Release time > 2 ms (latching or contact sticking).  
Loaded conditions (resistive load: 12 V; 4 mA;  
(15 mA peak); operating frequency: 170 Hz)  
Life expectancy: min. 107 operations with a failure rate  
of less than 10-8 with a confidence level of 90%.  
! Cropped and/or preformed leads  
Coils  
All characteristics are measured using the Philips  
Standard Coil. For definitions of the Philips Standard  
Coil, refer to “Application Notes” in the Reed Switch  
Technical & Application Information Section of this  
catalog.  
End of life criteria:  
Contact resistance > 2Ω after 4 ms  
Release time > 0.7 ms (latching or contact  
sticking). Switching different loads involves  
different life expectancy and reliability data. Further  
information is available on request.  
Life expectancy and reliability  
The life expectancy data given below are valid for a  
coil energized at 1.25 times the published maximum  
operate value for each type in the RI-21 series.  
Mechanical Data  
Contact arrangement is normally open; lead finish is  
tinned; net mass is approximately 190 mg; and can be  
mounted in any position.  
No load conditions (operating frequency: 100Hz)  
Life expectancy : min. 108 operations with a failure  
rate of less than 10-9 with a confidence level of 90%.
