Low Signal Relay

G6E

Precautions

■ Precautions for Correct Use

Long-term Continuously ON Contacts

Using the Relay in a circuit where the Relay will be ON continuously

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. We recommend

using a latching relay (magnetic-holding relay) in this kind of circuit. If

a single-side stable model must be used in this kind of circuit, we rec-

ommend using a fail-safe circuit design that provides protection

against contact failure or coil burnout.

Installation

Do not reverse the polarity of the coil (+, -).

Provide sufficient space between Relays when mounting two or more

on the same PCB, as shown in the following diagram.

Wiring

Refer to the following diagram when wiring to switch a DC load. The

difference in polarity applied to the contacts will affect the endurance

of the Relay due to the amount of contact movement. To extend the

endurance characteristics beyond the performance ratings, wire the

common (pin 7) terminal to the positive (+) side.

Ultrasonic Cleaning

Do not use ultrasonic cleaning on standard relay models. Doing so

may result in resonance, coil burnout, and contact adhesion within

the Relay.

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

°C. Do not put the Relay in a cold clean-

ing bath immediately after soldering.

■ Hints on Correct Use

Single-winding type (G6EU)

Example of low-power consumption driver circuit

1. This is an example of a driver circuit that allows Model G6E to

function as a normal relay with a normal switching pulse input.

2. The relay is set by an abrupt current charged to capacity C. This

current flows in the relay via diode D

3. The relay is reset by the discharge current of C flowing in the relay

via transistor TR and C.

Note: 1. Give adequate consideration to the circuit constant when

actually using this circuit, confirming the set and reset status

of the relay.

2. OMRON owns the patent on this circuit. Consult OMRON

when using this circuit.
