... Construction ■ SEALING Unsealed Relays of this type are intended for manual soldering. No measures are taken against penetration of flux and cleaning solvent into the relay. This type of relay cannot be immersion-cleaned. Semi-Sealed Special design construction prevents flux from penetrating into the relay housing, for example, due to capillary action up the terminals when the relay is soldered onto a PCB ...

... Internal Connections (Bottom View) Mounting orientation mark ■ Built-in Diode A diode is built into some relays, wired in parallel with the coil to absorb the counterelectromotive force (counter emf) generated by the coil. ■ Built-in Operation Indicator Some relays are provided with a light-emitting diode (LED), wired in parallel with the coil. This permits a fast-check of the relay’ ...

... Mounting Orientation Mark On the top of all OMRON relays is a mark indicating where the relay coil is located. Knowing the coil location aids in designing PCBs when spacing components. Also, pin orientation is easy to discern when automatic or hand-mounting relays. ...

... Moving Loop System In the U.S.A., the National Association of Relay Manufactures (NARM) in April 1984, awarded OMRON for monumental advances in relay technology, as embodied in the Moving Loop System. This unique relay construction maximizes electrical and permanent magnet energy. A high-efficiency magnet adds to the magnetic flux of the relay coil, which also allows for tighter packing of relay parts. Relays having such a coil are known as “ ...

... A current which serves as a reference in determining the perfor- mance of the relay contacts. This value will never exceed the current flow. When using a relay, do not exceed this value. Contact Form OMRON uses the following relay terminology for the various polarity and switch configurations. 1 FORM A: SPST-NO 1 FORM B: SPST-NC ...

This value may vary, depending on operating frequency, operating conditions, expected reliability level of the relay, etc always recommended to double-check relay suitability under actual load conditions. In Omron catalogs, the minimum permissible load of each relay is indicated as a reference value. It indicates failure level at a reliability ). λ -6 level of 60% (λ ...

... Also, even though OMRON relays are individually tested a num- ber of times, and each meets strict requirements, a certain testing tolerance is permissible. When a high-precision product uses many components, each depends upon the rated performance thresholds of the other components ...
Page 11
... Moreover, when a current is applied to the contact, heat is generated on the contacts, raising the coil temperature even higher (however, with relays whose switching current is rated lower, this rise is insignificant). Temperature Rise by Pulsating Voltage ...

... Incorrect I C Correct Voltage Considerations for AC Relays The voltage applied to the relay must be a sine wave. When a com- mercial power source is used, there should be no problem. However stabilized power source is used, either chatter or abnormal heating may occur, depending on the wave distortion of the power source ...

... The higher the counter emf, the greater the damage to the contacts. This may result in a significant decrease in the switching capacity of DC-switching relays. This is because, unlike the AC-switching relay, the DC-switching relay does not have a zero-cross point. Once arc has been generated, it does not easily diminish, prolonging the arc time ...

... PCBs having a thickness of 0.8, 1.2, 1.6, or 2.0 mm are generally used. A PCB that is 1.6 mm thick is best for mounting a PCB relay, considering the weight of the relay and the length of the terminals. (The terminal length of OMRON relays is 3, 3.5, or 4.0 to 5.0 mm.) 3.5 ■ Terminal Hole Diameter and ...

... Exposure to gases containing substances such as sulfuric acid, nitric 2 acid, or ammonia can cause malfunctions such as faulty contacting in relays. They can also cause the copper film of a PCB to corrode, or prevent positive contacts between the PCB’s connectors. Of the gases mentioned, nitric acid is particularly damaging as it tends to accelerate the silver migration ...

... When using a relay, be sure to check the mini- mum mounting interval. Also, if multiple PCBs with relays are mounted to a rack, the temper- ature may rise. In this case, preventive measures must be taken so that the ambient temperature falls within the rated value. ...

... The following tables list the processes required for mounting a relay onto a PCB and the points to be noted in each process. Process 1: Placement Do not bend any terminal of the relay to use self-clinching relay or the relay may malfunction recommended to use magazine-packaged self-clinching relays for placement onto the PCB. Possibility of Automatic Placement Construction Unsealed ...
