The document describes the features and characteristics of the RI-60 series ultra-miniature dry-reed switch. The switch is hermetically sealed in a gas-filled glass envelope and has a single-pole, single-throw structure with normally open contacts. It can 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.
The document describes the Coto RI-60 Series, which consists of ultra-miniature dry-reed switches hermetically sealed in a gas-filled glass envelope. These single-pole, single-throw (SPST) switches feature normally open contacts and are actuated by electromagnets or permanent magnets. They are designed for use in relays, sensors, and pulse counters, with contact layers made of gold or sputtered ruthenium.
| Contact Layers | Gold, sputtered ruthenium |
|---|---|
| Switched Voltage DC (max) | 200 V |
| Switched Current DC (max) | 500 mA |
| Operating Temperature Range | -55°C to +125°C |
| Storage Temperature Range | -55°C to +125°C |
| Resonant Frequency (typ.) | 11300 Hz |
The criteria are contact resistance greater than 2 ohms after 2.5 ms or release time greater than 2.5 ms (latching or contact sticking).
Yes, the leads can be welded.
The switch can withstand soldering heat in a bath at 350 +10° C for 3.5 +0.5 s.
