& mr82 series 9 notes on correct use 1. notes on contact load make sure that the contact load is within the specified range; otherwise, the lifetime of the contacts will be shortened considerably. note that the running performance shown is an example, and that it varies depending on parameters such as the type of load, switching frequency, driver circuit, and ambient temperature under the actual operating conditions. evaluate the performance by using the actual circuit before using the relay. 2. driving relays - if the internal connection diagram of a relay shows + and - symbols on the coil, apply the rated voltage to the relay in the specified direction. if a rippled dc current source is used, abnormalities such as beat at the coil may occur. - the maximum voltage that can be applied to the coil of the relay varies depending on the ambient temperature. generally, the higher the voltage applied to the coil, the shorter the operating time. note, however, that a high voltage also increases the bounce of the contacts and the contact opening and closing frequency, which may shorten the lifetime of the contacts. - if the driving voltage waveform of the relay coil rises and falls gradually, the inherent performance of the relay may not be fully realized. make sure that the voltage waveform instantaneously rises and falls as a pulse. - for a latching relay, apply a voltage to the coil according to the polarity specified in the internal connection diagram of the relay. - if a current is applied to the coil over a long period of time, the coil temperature rises, promoting gene ration of organic gas inside the relay, which may result in faulty contacts. in this case, use of a latching relay is recommended. - the operating time and release time indicate the time required for each contact to close after the voltage has been applied to or removed from the coil. however, because the relay has a mechanical structure, a bounce state exists at the end of the operating and release times. furthermore, because additional time is required until the contact stabilizes after being in a high-resistance state, care must be taken when using the relay at high speeds. 3. operating environment - make sure that the relay mounted in the application set is used within the specified temperature range. use of a relay at a temperature outside this range may adversely affect insulation or contact performance. - if the relay is used for a long period of time in highly humid (rh 85% or higher) environment, moisture may be absorbed into the relay. this moisture may react with the nox and sox generated by glow discharges that occur when the contacts are opened or closed, producing nitric or sulfuric acid. if this happens, the acid produced may corrode the metallic parts of the relay, causing operational malfunction. - because the operating temperature range varies depending on the humidity, use the relay in the temperature range illustrated in the figure below. prevent the relay from being frozen and avoid the generation of condensation. - the relay maintains constant sealability under normal atmospheric pressure (810 to 1,200 hpa). its sealability may be degraded or the relay may be deformed and malfunction if it is used under barometric conditions exceeding the specified range. - the same applies when the relay is stored or transported. keep the upper-limit value of the temperature to which the relay is exposed after it is removed from the carton box to within 50c. - if excessive vibration or shock is applied to the relay, it may malfunction and the contacts remain closed. vibration or shock applied to the relay during operation may cause considerable damage to or wearing of the contacts. note that operation of a snap switch mounted close to the relay or shock due to the operation of magnetic solenoid may also cause malfunctioning. 4. notes on mounting relays - when mounting a relay onto a pc board using an automatic chip mounter, if excessive force is applied to the cover of the relay when the relay is chucked or inserted, the cover may be damaged or the characteristics of the relay degraded. keep the force applied to the relay to within 1 kg. - avoid bending the pins to temporarily secure the relay to the pc board. bending the pins may degrade sealability or adversely affect the internal mechanism. - it is recommended to solder the relay onto a pc board under the following conditions: <1> reflow soldering refer to the recommended soldering temperature profile. <2> flow soldering solder temperature: 250c max., time: 5 to 10 seconds, preheating: 100c max./1 minute max. <3> manual soldering solder temperature: 350c, time: 2 to 3 seconds - ventilation immediately after soldering is recommended. avoid immersing the relay in cleaning solvent immediately after soldering due to the danger of thermal shock being applied to the relay. - use an alcohol-based or water-based cleaning solvent. never use thinner and benzene because they may damage the relay housing. - do not use ultrasonic cleaning because the vibration energy generated by the ultrasonic waves may cause the contacts to remain closed. 5. handling - relays are packaged in magazine cases for shipment. if a space is created in the case after some relays have been removed, be sure to insert a stopper to secure the remaining relays in the case. if relays are not well secured, vibration during transportation may cause malfunctioning of the contacts. - exercise care in handling the relay so as to avoid dropping it or allowing it to fall. do not use a relay that has been dropped. if a relay drops from a workbench to the floor, a shock of 9,800 m/s2 (1,000 g) or more is applied to the relay, possibly damaging its functions. even if a light shock has been applied to the relay, thoroughly evaluate its operation before using it. - latching relays are factory-set to the reset state for shipment. a latching relay may be set, however, by vibration or shock applied while being transported. be sure to forcibly reset the relay before using it in the application set. also note that the relay may be set by unexpected vibration or shock when it is used in a portable set. - the sealability of a surface-mount relay may be lost if the relay absorbs moisture and is then heated during soldering. when storing relays, therefore, observe the following points: <1> the storage humidity must be no more than 70% rh. the recommended storage period is 3 months maximum. <2> to store the relay for 3 months or longer, keep the storage humidity to within 50% rh. do not store the relay for more than 6 months. ?
