Coils with No Diode – Another Optimized Solution from Sun
 |
Sun Hydraulics now offers a selection of 770 (round) coils without transient voltage spike, or TVS, surge suppression diodes. |
The TVS diodes are included in DC coils to clamp the voltage spikes that occur when the coils are de-energized. The TVS diodes protect the electrical system from flyback voltage.
The new coils without TVS diodes should only be used when surge suppression is included elsewhere in the electrical system. Note: The TVS diode may need to be omitted in some systems, some with certain brand electrical controllers for example. Controller manufacturers can advise whether a TVS diode is necessary or must be omitted.

Note: These model codes are similar to model codes for coils with TVS diodes. Model codes for coils without TVS diodes simply have the suffix N. Only those shown above are available.
To Order:
Coils may be ordered separately or assembled to cartridges. Use the model codes above to order coils separately. For coils assembled to cartridges, omit the first three characters of the coil model code and append to the cartridge model code.
Ordering examples:
- Model code DLDA XCN-912N describes a 2-way, solenoid-operated directional spool valve, 12 VDC coil with Deutsch DT04-2P connector, without the diode.
- Model code DLDA XCN-912 describes the same valve and coil assembly with the diode.
