Datasheet DK (Panasonic) - 9

Power Relays ( Over 2 A ) DK RELAYS ● Minimum switching load is a guide to the lower ● Specification values of operate ( set ) voltage and current limit of switching under the micro-load. release ( reset ) voltage were measured with a relay This parameter is changed by the condition, such as oriented terminals down. switching times, environment condition, and expected Set the relay facing the terminals downward when reliability. operate ( set ) voltage and release ( reset ) voltage are Therefore, Panasonic Industry Co., Ltd. cannot assure measured. the reliability. ● Latching type is recommended when the relay is When the relay is used lower than minimum switching continuously energized. load, reliability is attrition. ● ( Latching type ) Please use the relay over minimum switching load. Regarding the set/reset pulse time of the latching type ● If the relay is dropped, it should not be used again. relay, it is recommended to apply rated voltage for ● When a source of silicone gas ( silicone rubber, silicone minimum 50 ms pulse across the coil to secure the sure oil, silicone coating materials and silicone filling operation considering the ambient temperature and materials etc. ) is used around the relay, the silicone condition change through service life. gas ( low molecular weight siloxane etc. ) may be ● ( Latching type ) produced. The relays are shipped from the factory in the reset state. The produced silicone gas may penetrate the plastic A shock to the relay during shipping or installation may case and enter the inside of the relay. When the relay change it to the set state. is kept and used in this condition, silicone compound Therefore, it is recommended to use the relay in a circuit may adhere to the relay contacts. which initializes the relay to the required state ( set or The silicon compound may be changed to the insulator reset ) whenever the power is turned on. which may cause the contact failure. Do not use any ● ( 1 Form A 1 Form B type ) source of silicone gas around the relay. Please note that when this relay operates or resets, both ● Do not use the relay in areas where flammable or the normally open ( N.O. ) and normally closed ( N.C. ) explosive gases from gasoline and thinner, etc., may contacts may turn ON simultaneously, which could be present. adversely affect the circuit. ● Please check the insulation distance between each ● The product specifications may be changed based terminal and ground. on product improvements and another reasons ● Please absolutely avoid the ultrasonic and high ( specification changes, Including production frequency vibration to the relay that adversely affects discontinuation ). its performance.
