**Notes:** 1) We recommend flux proofed types for the flat pack version. - 2) We recommend flux proofed types for a clean environment (free from contaminations like H2S, SO2, NO2, dust, etc.). We suggest to choose plastic sealed types and validate it in real application for an unclean environment (with contaminations like H2S, SO2,NO2, dust, etc.). - 3) Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays on PCB. - 4) The customer special requirement express as special code after evaluating by Hongfa. e.g. (210) stands for pick-up voltage less than 70% of norminal voltage. e.g. (414) stands for wide coil pin type. - 5) Standard tube packing length is 550mm. Any special requirement needed, please contact us for more details. - 6) For products that should meet the explosion-proof requirements of "IEC 60079 series",please note [Ex] after the specification while placing orders.Not all products have explosion-proof certification,so please contact us if necessary, in order to select the suitable products. ## **OUTLINE DIMENSIONS, WIRING DIAGRAM AND PC BOARD LAYOUT** Unit: mm **==> picture [89 x 8] intentionally omitted <==** **----- Start of picture text -----**
