Overview

The TQ2-L2-24V is a high-sensitivity, dual-coil latching signal relay designed for low-level switching applications. This DPDT (2 Form C) relay features a compact through-hole package and is optimized for telecommunications and precision instrumentation where power efficiency is critical. Because it is a latching relay, it maintains its contact state without continuous power, requiring only a brief pulse to set or reset.

Why Choose This Part

The dual-coil latching design allows for minimal energy consumption, as power is only required for 3 ms during switching. Its gold-clad silver contacts provide high contact reliability for low-level signals, while the 24VDC coil operates at a low current of 12.5 mA. The compact footprint and UR/CSA approvals make it a versatile choice for dense PCB layouts in regulated environments.

Applications

Telecommunications Equipment
Switching signal lines in private branch exchange (PBX) systems and central office equipment.
Battery-Powered Instrumentation
Ideal for handheld test equipment where the latching mechanism eliminates the constant power draw of a standard relay coil.
Industrial Control Systems
Used for logic-level switching and status feedback in PLC systems and automation controllers.
Alarm and Security Systems
Reliable state retention for sensor loops and alert indicators during power fluctuations.

Getting Started

When designing with this dual-coil relay, ensure the drive circuit can provide at least 12.5 mA at 24VDC for the 3 ms operate time. Engineers must implement a H-bridge or dual-switch driver to pulse the Set and Reset coils independently. Always include flyback diodes across both coils to protect driving transistors from inductive spikes during de-energization.
