Hints on Correct Use

Single-winding type (G5AU)

Example of low-power drive circuit

1. The figure below shows a drive circuit (JAPAN PAT. NO. 1239293)

in which the latching relay can function like a general-purpose

relay from a normal input pulse for switching.

2. Use a charging current of capacitor C to operate the latching

relay, which flows suddenly through diode D1, capacitor C, latch-

ing relay, and diode D2, and the relay contacts will be put in the

locked state.

3. Use a discharging current of capacitor C to release the latching

relay, which flows through transistor TR, capacitor C, and the

latching relay.

Note: 1. When applying the relay for practical use, make sure of the

set or reset state of the relay; then determine the circuit con-

straints.

2. Because OMRON possesses the patent of this drive circuit,

contact OMRON when adopting it.

Precautions

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.

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.

Certain Precautions on Specifications and Use

1. Suitability for Use. Seller shall not be responsible for conformity with any stan-

dards, codes or regulations which apply to the combination of the Product in

Buyer's application or use of the Product. At Buyer's request, Seller will pro-

vide applicable third party certification documents identifying ratings and limi-

tations of use which apply to the Product. This information by itself is not

sufficient for a complete determination of the suitability of the Product in com-

bination with the end product, machine, system, or other application or use.

Buyer shall be solely responsible for determining appropriateness of the par-

ticular Product with respect to Buyer's application, product or system. Buyer

shall take application responsibility in all cases but the following is a non-

exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical

interference, or conditions or uses not described in this document.

(ii) Energy control systems, combustion systems, railroad systems, aviation

systems, medical equipment, amusement machines, vehicles, safety

equipment, and installations subject to separate industry or government

regulations.

(iii) Use in consumer products or any use in significant quantities.

(iv) Systems, machines and equipment that could present a risk to life or

property. Please know and observe all prohibitions of use applicable to this

product.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS

RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM

AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT

THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE

INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.

2. Programmable Products. Seller shall not be responsible for the user's pro-

gramming of a programmable product, or any consequence thereof.

3. Performance Data. Performance data given in this publication is provided as

a guide for the user in determining suitability and does not constitute a war-

ranty. It may represent the result of Seller's test conditions, and the users must

correlate it to actual application requirements. Actual performance is subject to

Seller's Warranty and Limitations of Liability.

4. Change in Specifications. Product specifications and accessories may be

changed at any time based on improvements and other reasons. It is our prac-

tice to change part numbers when published ratings or features are changed,

or when significant construction changes are made. However, some specifica-

tions of the Product may be changed without any notice. When in doubt, spe-

cial part numbers may be assigned to fix or establish key specifications for

your application. Please consult with your Seller representative at any time to

confirm actual specifications of purchased Product.

5. Errors and Omissions. The information in this publication has been carefully

checked and is believed to be accurate; however, no responsibility is assumed

for clerical, typographical or proofreading errors, or omissions.

6. RoHS Compliance. Where indicated, our products currently comply, to the

best of our knowledge as of the date of this publication, with the requirements

of the European Union's Directive on the Restriction of certain Hazardous

Substances ("RoHS"), although the requirements of RoHS do not take effect

until July 2006. These requirements may be subject to change. Please consult
