Key Features

  • 5 V DC coil voltage enabling direct drive from standard logic-level GPIO or transistor outputs without additional voltage boosting
  • SPST hermetically sealed reed contacts offering high isolation resistance exceeding 10^9 ohms and switching lifetimes above 100 million operations
  • Compact SIL or DIL through-hole package providing easy PCB integration with minimal footprint in instrumentation and ATE applications

Applications

The S8-0504 reed relay is used in automated test equipment (ATE), data acquisition systems, and medical instrumentation where low-leakage, high-isolation switching of small signals is required. Its 5 V coil allows direct microcontroller or logic interface without external driver ICs. The device is also popular in telecommunications switching matrices and security sensor circuits for its long service life and reliable hermetic contact sealing.

Frequently Asked Questions

What coil voltage does the S8-0504 require and can it be driven directly from a 5 V microcontroller GPIO?

The S8-0504 has a 5 V DC coil voltage, allowing direct drive from a 5 V microcontroller GPIO or a small NPN transistor switch. The typical coil resistance is around 500 ohms, resulting in a coil current of approximately 10 mA at 5 V, which is within the drive capability of standard transistor switch circuits.

What switching configuration does the S8-0504 provide and what maximum load can it handle?

The S8-0504 is a SPST (Single-Pole Single-Throw) reed relay with normally-open contacts, closing when the 5 V coil is energized. Reed relay contacts typically switch loads up to 10 W or 1 A at voltages up to 200 V DC, making the S8-0504 suitable for low-level signal switching in measurement and test equipment.

How does the hermetic sealing of the S8-0504 reed contacts benefit long-term reliability in instrumentation?

The hermetically sealed glass envelope enclosing the S8-0504 reed switch contacts prevents contamination from flux, moisture, and corrosive gases. This sealing maintains contact resistance below 100 milliohms over more than 100 million switching operations, ensuring stable and repeatable performance in precision measurement instruments over decades of service.

In which sectors is the Cynergy3 S8-0504 commonly specified as a preferred relay solution?

The S8-0504 is commonly specified in automated test equipment (ATE) systems, medical diagnostic instruments, and industrial data loggers where its 5 V coil, SPST configuration, and hermetic reed contacts provide reliable isolation of sensitive analog signals below 1 mA without the contact bounce issues found in mechanical armature relays.
