ITT Cannon DL Series Connectors

HIGH-DENSITY ZIF DL CONNECTORS

ITT Cannon DL series connectors are versatile, high-density ZIF connectors (zero-insertion force) with 60 contact, 96 contact and 156 contact versions. The DL series are excellent medical connectors and are suited for other applications requiring no sliding force during mating and unmating, such as sound, lighting and entertainment equipment. The new ITT Cannon DLM shielded metal connector offers a stronger, light-weight aluminum housing that is nickel-plated for maximum shielding. For more details on the ITT Cannon DL series of zero-insertion force (ZIF) connectors, please see the product specifications below.

FEATURES

ITT CANNON DL SERIES CONNECTORS FEATURES

  • True Zero Insertion Force (ZIF) Connectors
    There is no build up of mating force typically associated with high pin count style connectors, so mating and un-mating is as easy as twisting a handle.

  • Long Mating Life
    10,000 matings minimum allows these connectors to be used in testing and burn in applications.

  • High Pin Count
    60, 96, 156, 260, 360, 624, 1248, and even 2496 contacts make the DL series one of the highest pin count per connector series available.

  • Wide Selection of Terminations
    Crimp, printed circuit, square post and solder buss style contacts give you maximum flexibility to wire your connectors.

  • New Nickel-Plated Aluminum Housings
    The DLM1/2/3 (60, 96 & 156 pin) versions are now available in a strong metal shell, fully EMI/RFI shielded version that can mate with the standard plastic housing version. This allows for easy upgrade to a shielded version without sacrificing intermatability of units already in the field.

  • Contact Wiping
    During mating, the contacts wipe lightly together, which helps clean the contact mating area and assures low contact resistance needed for digital or low current applications.

Note
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 value recorded using the methods specified by International Electro-Technical Commission Document 48 (1975). 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; 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.
