Overview

The TQ2SA-5V-X is a compact, surface-mount telecom relay featuring a DPDT (2 Form C) contact arrangement. It is designed for high-density mounting and offers high sensitivity with a nominal 140mW operating power. The relay provides reliable switching with gold-clad silver nickel contacts, making it suitable for low-level signal applications.

Why Choose This Part

This relay features a low profile height of 6mm and a small footprint for space-constrained PCB designs. It offers fast switching performance with an operate and release time of only 4ms. The gold-clad contacts ensure long-term contact reliability even when switching low-level signals.

Applications

Telecommunications Equipment
Ideal for switching signal lines in telephone exchanges, PBX systems, and networking hardware.
Test and Measurement
Used in automated test equipment (ATE) for routing low-level signals with minimal contact resistance.
Industrial Control
Provides galvanic isolation and signal switching in PLC output modules and sensor interfaces.
Medical Instrumentation
Suitable for low-power signal routing in diagnostic and monitoring equipment requiring high reliability.

Getting Started

When integrating this relay, ensure the drive circuit can provide the nominal 28.1mA coil current at 5VDC. Use a flyback diode across the coil to protect driving transistors from inductive spikes. For surface mount assembly, follow the recommended reflow profile to avoid damaging the internal mechanical components.
