ITT Cannon SLC Series Snap Lock Circular Connectors

HARSH-ENVIRONMENT SNAP LOCK CIRCULAR CONNECTORS

The ITT Cannon Snap Lock Environmental series (SLC) is an environmentally-sealed, circular connector created for printed circuit board (PCB), cable-to-cable or bulkhead applications. The SLC snap lock series is environmentally-sealed against sand and dust and are designed for use under-the-hood, withstanding harsh off-road contaminants including oil and antifreeze. SLC snap lock connectors are user-friendly and easy to assemble, with an audible and tactile feedback. SLC connector contacts will handle up to 5 amps continuous at a fully-rated temperature range of -40°C to +125°C. The SLC series is available as a 5 pin connector and a 10 pin connector. For full details on ITT Cannon SLC series snap lock circular connectors, see the product specifications below.

FEATURES

ITT CANNON SLC SERIES FEATURES

  • High-Quality Circular Connector
    With silicone mating, interfacial and wire seals that resists even the harshest of contaminants.

  • Shared Tooling
    SLC connectors use the same proven contact as SLE and CLC connectors and are assembled using the same crimping and low cost extraction tools.

  • Convertible Mounting
    Simple snap-on mounting plates allow users to convert from inline connections to wall mounting, minimizing inventoried components.

  • Strong Connector Snap Locks
    Snap locks are located at either side of the SLC connectors. These locks are molded into the connector bodies and lock the connectors together when mated. To unmate, depress the snap locks simultaneously and pull the connectors apart.

TEST PARAMETERS

ITT CANNON SLC SERIES TEST PARAMETERS

SLC Products are designed to meet Cannon specifications CS-206, CS-210 and CS-216. Items of most general interest to users are designers are listed below.
Test Description
Requirements
Environmental Sealing
Sand and dust MIL-STD-202 method 110 Test Condition A
5% salt spray 96 hours
10 cycles of 24 hours, 90-98% humidity
Steam Cleaning/Pressure Wash 95°C, 375 Cycles 750 PSIG
Solvent Resistance/Immersion (see 3,2,3,9)
Thermal Shock 100 Cycles -40°C to +150°C +/- 3°C
Contact Crimp Tensile Strength
The minimum tensile load required to separate the wire from the contact, either by pulling the wire out of the crimp joint or by joint or by breaking the wire within the crimp joint shall not be less than the applicable limits as specified. Wire breakage or contact damage not due to crimping at less than tensile loads shall not constitute a failure.

Vibration
Connectors shall be subjected to random vibration in accordance with MIL-STD-1344, Method 2005.1, test condition VI for 20 hours along each of the following three axes:

Direction

Grms

Radial Axis of connector (Y)

10.2

Longitudinal axis of connector (Z)

10.2

Electrical continuity of the connectors shall be monitored during the last 20 minutes sweep in each axis with a test current of 100 milliamps or less and a test voltage less than 2VDC. Electrical discontinuities in excess of 10 microseconds shall be cause of failure.


Durability
Connectors shall be subjected to 25 cycles of mating and unmating at room temperature. Following this test there shall be no evidence of damage to the contacts, contact plating, connector housing or seals which may prove detrimental to reliable performance of the connector.
Contact
Contacts shall not be displaced greater than 0.030 inches from the connector body when a force of 10 pounds is applied. When this test follows maintenance again the same contacts shall be tested.
Maintenance Aging
Consist of subjecting each wired receptacle to 5 cycles of removal and reinsertion of 20% of the contacts or a minimum of 5 per connector with approved tooling.
Mating and Separating Force
The maximum force required to mate the plug and receptacle shall be 10 pounds. The maximum force required to separate the plug and receptacle shall be five pounds. The rate of travel shall be one inch per minute.
Solvent Resistance Immersion
Connectors shall be subjected to the following fluids at the temperature and length of time specified. Following the fluid dip or immersion, the connectors shall be immersed to a depth of 2 to 12 inches in a 5% salt-water solution for 24 hours at room temperature. At the completion of the salt-water immersion test, while still immersed, the connectors shall meet the insulation resistance requirement specified herein.

(1) Dip: Connectors shall withstand a one second dip and a three minute air dry for a total of 80 cycles.
(2) Immersion: Connectors shall withstand immersion for one hour.
Temperature Life
Connectors shall be subjected to a temperature of 150°C ± 3°C for a period of 1000 hours. At the end of the temperature soak period and after removal from the chamber, the connectors shall meet the insulation resistance and dielectric withstanding voltage requirements specified herein. Connectors shall be operated at rated current throughout the duration of the temperature life test. Upon removal from the chamber at the conclusion of the test, the connectors shall show no visual signs of damage, which may be detrimental to the performance of the connector.
Thermal Cycle
Connectors shall be subjected to 100 thermal cycles from -40°C to +150°C. One cycle shall consist of the transitions from room temperature to -40°C to +150°C, and from 150°C to room temperature. One cycle shall be accomplished in a three-hour period with a minimum stabilization period of 15 minutes at each temperature extreme.
