Construction”. 1)2 S: Plastic: sealed Nil:. Flux proofed
Version 3: 5.0mm
Contact material A: AgSnO2(Character (A) may follow the batch number)
Special code?) XXX: Customer special requirement Nil: Standard
Notes: 1) We recommend flux proofed types for a clean environment (free from contaminations like H2S, SOz, NOz, dust, etc.).
We suggest to choose plastic sealed types and validate it in real application for an unclean environment (with contaminations
like H2S, SOz, NOz, dust, etc.).
2) Contact is recommended for suitable condition and specifications if water water cleaning or surface process is involved in assembling relays
on PCB.
3) The customer special requirement express as special code after evaluating by Hongfa. e.g.(335) stands for product in accordance to
IEC 60335-1 (GWT).
4) Two packing methods available: plastic tray package, tube package,Standard tube packing length is 616mm. Any special requirement
needed, please contact us for more details.
5) For products that should meet the explosion-proof requirements of "IEC "IEC 60079 series",please note [Ex] after the specification while
orders.Not all products have explosion-proof certification,so please contact us if necessary, in order to select the suitable products.
