2025-04-26
Introduction
The TXD2-3V relay is High Breakdown Voltage Relay with high sensitivity, reliability, and robust construction. Let’s learning the key features, typical applications, packing style, and selection criteria for the TXD2-3V Panasonic relay.
TXD2-3V Relay Features
For high-performance applications,suitable for industrial, automotive, telecommunications, and consumer electronics.
1. Complies with EN60950 Supplementary Insulation Standards
Meet the EN60950 safety standard, ensuring sufficient insulation between the coil and contacts. This compliance is crucial for preventing electrical hazards in high-voltage applications.
• Clearances: 2.0 mm .079 inch or more
• Creepage distance: 2.5 mm .098 inch or more
2. High Breakdown Voltage (3,000 V Between Contact and Coil)
With a 3,000 V breakdown voltage between contact and coil. The body block construction of the coil that is sealed formation.
3. High Sensitivity (200 mW Nominal Operating Power)
Use highly efficient polar magnetic circuit “seesaw balance mechanism”. Achieve a nominal operating power of 200 mW.
4. High Contact Capacity (2 A, 30 V DC)
5. Gold-Clad Crossbar Twin Contacts for Superior Reliability
The relay features gold-clad crossbar twin contacts, ensuring low contact resistance, minimal arcing, and long-term reliability. Additionally, gas-expelling materials during manufacturing enhance durability by preventing oxidation.
6. Exceptional Vibration and Shock Resistance
Functional shock resistance: 750 m/s
Destructive shock resistance: 1,000 m/s
Functional vibration resistance: 10 to 55 Hz (at double amplitude of 3.3 mm .130 inch)
Destructive vibration resistance: 10 to 55 Hz (at double amplitude of 5 mm .197 inch)
7. Sealed Construction for Automatic Washing
