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.
N-Coils

Coils now available without TVS surge suppression diodes:

	Connectors
Voltage	DIN 43650 Form A	Amp Jr. Timer	Twin Leads	Metri Pack	Deutsch DT04-2P
12 VDC	770-212N	770-612N	770-712N	770-812N	770-912N
14 VDC	770-214N			770-814N	770-914N
24 VDC	770-224N	770-624N	770-724N	770-824N	770-924N

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.
