Nil: Standard
Notes: 1) Dust protected version is recommended.
2) Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays on PCB.
3) If parallel diode, Zener Diode or other components are required, please contact Hongfa for more technical supports.
4) The customer special requirement express as special code after evaluating by Hongfa. e.g. (170) stands for flasher load
