TX2-4.5V-TH Overview

Part: TX-TH Series (TX2-5V-TH)

Type: Electromechanical Signal / Power Relay

Description: 2 Form C low-profile signal relay with 2 A 30 V DC nominal switching capacity and capability to handle up to 7.5 A controlled inrush current.

Operating Conditions:

  • Supply voltage: 5 V DC nominal coil voltage (1.5 V to 48 V DC options across family)
  • Operating temperature: -40 °C to +85 °C (up to 24 V coil), -40 °C to +70 °C (48 V coil)
  • Operating humidity: 5% to 85% RH (non-condensing, non-freezing)

Key Specs:

  • Contact arrangement: 2 Form C (DPDT)
  • Contact rating: 2 A at 30 V DC, 0.5 A at 125 V AC (resistive load)
  • Maximum switching voltage: 220 V DC, 250 V AC
  • Maximum switching current: 7.5 A (with NO and COM pins paralleled per precaution)
  • Maximum switching power: 60 W, 60 VA (resistive load)
  • Initial contact resistance: Max. 100 mΩ (measured at 6 V DC, 1 A)
  • Coil power consumption: 140 mW nominal (single side stable, 1.5 to 24 V DC)
  • Operate / Release time: Max. 4 ms / Max. 4 ms (excluding bounce)
  • Breakdown voltage: 2,000 Vrms (between contact and coil, 1 min)
  • Surge breakdown voltage: 2,500 V (2 × 10 μs, between contact and coil)

Features:

  • High breakdown voltage of 2,000 V between contact and coil, 1,000 V between open contacts
  • High surge breakdown resistance up to 2,500 V (Bellcore)
  • High operating sensitivity of 140 mW nominal operating power
  • Sealed construction allows automatic washing
  • Single side stable, 1-coil latching, and 2-coil latching options available

Applications:

  • Air-conditioning control (solenoid load)
  • High-capacity load control

Package:

  • Standard PC board terminal (15.0 mm × 7.4 mm × 8.2 mm)
  • Surface-mount terminal (SA low-profile and SS space-saving types)
