G5V-2 Low Signal Relay

General-purpose, Low-cost, Two-pole Relays for Signal Circults

  • General-purpose DIL terminal layout.
  • Wide switching power of 10 µA to 2 A.
  • Fully-sealed type Relays standardized with bifurcated crossbar contacts. Highly reliable in addition to its high environment resistance.
  • Conforms to FCC Part 68 (impulse withstand voltage of 1,500 V for 10 x 160 νs between coil and contacts and between contacts of the same polarity).
  • High dielectric strength at 1,000 VAC between coil and contacts, and 750 VAC between contacts of the same polarity.
  • UL and CSA standard approved.
RoHS Compliant

NOTE: The above values are initial values.

1.The contact resistance was measured with 10 mA at 1 VDC with a voltage drop method.

2.The insulation resistance was measured with a 500 VDC megohmmeter applied to the same parts as those used for checking the dielectric strength.

3.This value was measured at a switching frequency of 120 operations/min and the criterion of contact resistance is 50 Ω. This value may vary depending on the switching frequency and operating environment.
Always double-check relay suitability under actual operating conditions.

Note:Each value has a tolerance of ±0.3 mm.

Correct Use

●Long-term Continuously ON Contacts

℃Using the Relay in a circuit where the Relay will be ON continu- ously for long periods (without switching) can lead to unstable contacts because the heat generated by the coil itself will affect the insulation, causing a film to develop on the contact surfaces. Be sure to use a fail-safe circuit design that provides protection against contact failure or coil burnout.

●Relay Handling

When washing the product after soldering the Relay to a PCB, use a water-based solvent or alcohol-based solvent, and keep the solvent temperature to less than 40.

℃ Do not put the Relay in a cold cleaning bath immediately after soldering.
