- **Notes:** 1) 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). - 2) Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays on PCB. - 3) For the loads which can bring high inrush current when relay contacts connect istantly (eg. lamp, capacitive load), AgSnO2 contact material is recommended on priority. - 4) For gold plated type, the min. switching current and min. switching voltage is 10mA 5VDC. - 5) The customer special requirement express as special code after evaluating by Hongfa. - 6) Two packing methods available: paper box package, plastic tray package,tube package.Standard tube packing length is 560mm. Any special requirement needed, please contact us for more details. - 7) 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 ## Outline Dimensions ## HF46F-G/ β–‘β–‘ -HS1 β–‘β–‘ (XXX) **==> picture [351 x 219] intentionally omitted <==** **----- Start of picture text -----**

Remark:1) The pin dimension of the product outline drawing is the size before tinning (it will become larger after tinning), and the mounting hole size is the recommended design size of the PCB board hole. The specific PCB board hole design size can be mapped and adjusted according to the actual product. - 2) In case of no tolerance shown in outline dimension: outline dimension ≀ 1mm, tolerance should be Β±0.2mm; outline dimension ＞ 1mm and ≀ 5mm, tolerance should be Β±0.3mm; outline dimension ＞ 5mm, tolerance should be Β±0.4mm. - 3) The tolerance without indicating for PCB layout is always Β±0.1mm. 78 ## **CHARACTERISTIC CURVES** ## MAXIMUM SWITCHING POWER ## ENDURANCE CURVE ## COIL TEMPERATURE RISE **==> picture [458 x 140] intentionally omitted <==** **----- Start of picture text -----**
