DL/DLM/DLD Temperature/Current Rating
The ambient temperature curves shown represent
the rated current carrying capacity of the Cannon
DL1/2/3/4, DLM1/2/3 and DLD1/2 electrical
connectors, derated to 80% of the values recorded
using the methods specified by International
Electro-Technical Commission Document 48
Current was applied to the total connector (all
contacts) in one-half ampere increments and
maintained at each current level until thermal
stability was achieved. A thermocouple inserted
into the ‘‘hottest area’’ of each connector then
measured the connector temperature at the same
time that an ambient temperature reading was
taken. The difference between the two measured
values is the heat rise or self-heating created solely
by the current flow, and this temperature rise for
the current level was deducted from the insulator
material rated temperature. These values were
then derated to 80% to obtain the curves shown.

How to Identify the Ideal DL Product for Your Application
Q. What type of actuation does the application require?
Q. Does the application require
plastic housing?
Q. Does the application require
metal housing?
Q. Does this application involve
low currents?
Q. Does this application involve standard currents of more than
100 milliamps?
Q. Does this application involve
higher than 5 amps?
Q. What
type of contact is required for this application?
Q. Does the application require
crimp contacts?
Q. Does the application require crimp tooling, with low or high
Q. Is an actuating
handle needed?
Q. Does the application require
fool-proof mating?
Q. How do I protect the wiring / cabling?
Q. When the DL5-260 series application
requires EMI / RFI
Q. Does the customer need to
protect the contacts when
connector is not mated?
A. Manual (turn handle cam) – DL / DLM series.
Blind mating (self cam) – DLD drawer series.
A. DL / DLD series.
A. DLM series (for EMI / RFI shielding).
DL4 series.
A. For 100 milliamps or less use 50µ inch gold contacts (Flat contacts
on Receptacle, and Bump contacts on Plug), see pages 52-53.
A. For more than 100 milliamps, use 20µ inch gold contacts
(Hermaphroditic Bump contact), see pages 52-53.
A. For higher than 5 amps use Buss contacts, see page 51.
A. Select the appropriate part number for the Plug and Receptacle
based on the number and type of contacts needed for this
application, see pages 12-13.
A. Order appropriate crimp contacts for the wire size used in this
application, see pages 50-53.
ɀ 50µ inch Gold (low current to 5 A applications) – Most
ɀ 20µ inch Gold (standard application)
ɀ Buss contacts (high amps-greater than 5 A)
A. For low volume of crimps:
Order loose contacts and order the appropriate hand tool,
see page 55.
For high volume of crimps (50,000 per year or more):
Order reeled contacts, see page 53, and contact Cannon’s Customer-
Use-Tooling to lease an automatic crimp machine, see page 59.
A. Actuating handles are ordered separately (except DL4 Series),
see page 47.
A. Order the polarizing posts to protect from erroneous mating,
see page 48.
A. Two Options:
ɀ Plastic Junction Shell with optional second entry cable clamp
kit, see page 46.
ɀ Metal Backshell available, see pages 44-45.
A. Order the EMI / RFI metal shielding shells or utilize the new DLM5
series without shield shell, see page 49.
A. Order the appropriate protective cover, see page 47.
