Remark: 1) In case of no tolerance shown in outline dimension: outline dimension ≤ 1mm, tolerance should be ±0.2mm; outline dimension ＞ 1mm and ≤ 5mm, tolerance should be ±0.3mm; outline dimension ＞ 5mm, tolerance should be ±0.4mm. - 2) The tolerance without indicating for PCB layout is always ±0.1mm. - 3) The width of the gridding is 2.52mm. ## **Notice** 1. Relay is on the “reset” status when being released from stock, with the consideration of shock risen from transit and relay mounting, relay would be changed to “set” status, therefore, when application ( connecting the power supply), please reset the relay to “set” or “reset” status on request. 2. In order to maintain “set” or “reset” status, energized voltage to coil should reach the rated voltage. Do not energize voltage to “set” coil and “reset” coil simultaneously. And also long energized time (more than 1 min) should be avoided. 3. Keep the product away from strong magnetic field during transportation, storage and application, to avoid change of set/reset voltage. ## Disclaimer The specification is for reference only. See to "Terminology and Guidelines" for more information. Specifications subject to change without notice. We could not evaluate all the performance and all the parameters for every possible application. Thus the user should be in a right position to choose the suitable product for their own application. If there is any query, please contact Hongfa for the technical service. However, it is the user’s responsibility to determine which product should be used only. - © Xiamen Hongfa Electroacoustic Co., Ltd.
