Overview

The TX2SA-5V is a high-sensitivity DPDT (2 Form C) telecom relay designed for surface-mount applications. It features gold-clad twin crossbar contacts and a compact SA-type package, making it ideal for high-density PCB layouts requiring reliable switching of low-level analog signals.

Why Choose This Part

The relay offers a high breakdown voltage of 2,000 V between contact and coil and outstanding surge resistance. Its AgPd contacts are specifically suited for low-level load analog circuits, and the sealed construction allows for automatic washing during the manufacturing process.

Applications

Telecom Switching
Ideal for switching signals in telephony and communication equipment due to high contact reliability.
Test and Measurement
Used in automated test equipment (ATE) for routing low-level signals with minimal contact resistance.
Medical Instrumentation
Provides signal isolation and switching in sensitive diagnostic hardware requiring high breakdown voltage.
Industrial Control Systems
Suitable for PLC output modules and signal routing in noisy industrial environments.

Getting Started

When designing with the TX2SA-5V, ensure the PCB footprint accounts for the SA-type surface-mount pads. Since this is a non-latching relay, the coil must remain energized with 5VDC at approximately 28.1 mA to maintain the switched state. Use a standard flyback diode across the coil pins to protect driving circuitry from inductive spikes during de-energization.

Also Consider

G6K-2F-Y-DC5 Omron - A common alternative telecom relay with a similar small footprint and 5V coil rating.
IM03GR TE Connectivity - An ultra-slim signal relay that offers high dielectric strength in a smaller physical volume for dense boards.
