Key Features
- 2-Form-C (DPDT) contact configuration provides two independent changeover contact sets in a single compact relay package, enabling simultaneous switching of 2 signal paths
- 3 V DC coil voltage with only 10 µA must-operate current allows direct actuation by low-power microcontroller outputs or CMOS logic gates without a transistor driver stage
- Ultra-sensitive coil design preserves battery life in portable instruments and IoT nodes where relay actuation energy must remain below 30 µW per switching event
Applications
The EE2-3TNU-L is designed for low-power signal routing in medical diagnostic instruments, portable test equipment, and IoT gateway modules where two signal paths must be switched simultaneously from a 3 V logic supply. Its ultra-low 10 µA coil current makes it ideal for battery-operated data acquisition systems and remote sensor units that switch infrequently but must maintain long standby life between relay actuations.

Frequently Asked Questions
How low is the coil drive current for EE2-3TNU-L and which circuits can drive it directly?
The EE2-3TNU-L requires only 10 µA must-operate current at 3 V coil voltage, which is well within the source current capability of most CMOS and TTL GPIO outputs rated at 4 mA to 8 mA. This means the relay can be driven directly by a microcontroller pin on STM32, nRF52, or similar 3.3 V MCUs without any intervening transistor or FET driver stage, simplifying the circuit and saving board space.
What does 2-Form-C (DPDT) mean for signal routing with EE2-3TNU-L?
2-Form-C means the EE2-3TNU-L contains 2 independent SPDT (changeover) contact sets, each with a normally-open (NO) and normally-closed (NC) terminal sharing a common (COM). This allows the relay to simultaneously route or disconnect 2 separate signal lines, which is useful for switching balanced audio lines, differential measurement paths, or paired control signals in test instrumentation and data acquisition equipment.
What contact current and voltage ratings does the EE2-3TNU-L support for signal switching?
As a signal relay, the EE2-3TNU-L contacts are rated for low-level switching typically in the range of 100 mA to 500 mA at 30 V DC, appropriate for analog measurement signals, digital bus lines, and logic-level control paths. These ratings are not suitable for mains AC or high-current DC loads; for those applications a power relay rated at 10 A or higher should be used instead.
When is EE2-3TNU-L a better choice than a solid-state relay or analog switch for signal routing?
The EE2-3TNU-L provides true galvanic isolation between coil and contacts with virtually zero off-state leakage current (below 1 nA), whereas solid-state relays have leakage currents of 1 µA to 10 µA and analog switches (like ADG series) have on-resistance of 2 Ω to 100 Ω that adds series error. For precision measurement applications requiring sub-millivolt signal fidelity or picoampere-level leakage control, the mechanical relay contact of EE2-3TNU-L is superior despite its slower switching speed of 1 ms to 10 ms.
