STEPS IN SELECTING THORKOM CONNECTORS To assist you in selecting and ordering our connectors for your specific application, we have some suggested guidelines to follow: 1. Type of cable to be used (jacketed, shielded, coil, straight, AWG of individual wire) 2. Where connector is used (bulkhead, cable to cable) 3. What are the current require- ments (volts, amps, etc.) 4. Size of connector and type (number of contacts, right angle or straight) 5. Strain relief (yes or no, if yes, type of backshell) 6. Type of approval connector needs to meet (U.L., CSA, VDE) All these questions, when answered, will help expedite the placing of your order and ensure your receiving the correct product.
