Notes: 1) The data shown above are initial values.
2) Maximum voltage refers to the maximum voltage which relay
coil could endure in a short period of time.
3) For products with rated voltage ≥ 48V, measures should be
taken to prevent coil overvoltage in order to protect coil in test
and application (eg. Connect diodes in parallel).

Notes: 1) 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).
2) Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays
on PCB.
3) For gold plated type, the min. switching current and min. switching voltage is 10mA 5VDC.
4) 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).
5) Two packing methods available: paper box package, tube package,Standard tube packing length is 535mm. 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.
