Circular Connectors CA/MS A&B C annon has re-introduced the widely used MS A&B product line with improved features. For corrosion protection we have changed the shell finish to an environmentally safe, zinc alloy plating. The plating is a high quality finish and uniform in color. The contacts, which are preloaded in the insulator, have been redesigned such that the solder cups remain in proper orientation and will not rotate during wiring termination. The contacts are also machined for strength and durability and plated with silver. The Cannon MS A&B design meets the performance requirements of the MIL-C-5015. The product is available in all the popular sizes and configurations in Class A (solid end bell) and Class B (split end bell versions).

The insulator kit includes a snap ring and insulator with preloaded contacts. The hardware kit includes the shell along with appropriate endbell (except box mount receptacles) and coupling nut (plug only). Step 1*: Remove tape from insulator. With the insulator and shell positioned as shown above, polarize insulator to desired position and place inside shell using the internal keyway as guide. Once inside the shell, the insulator cannot rotate. However, until the snap ring is applied in step 2, the insulator is not captivated in the shell. Step 2: After insulator is seated in shell, install the snap ring on the rear of the connector. Slightly compress ring and insert into recessed area just above the insulator. If not completely in place, manipulate the snap ring with finger until visual or audible seating confirmation is made. No tooling is required. Step 3: Confirm insulator is fixed inside shell by applying slight force on the engaging side of the insulator. If properly installed, the insulator can not be pushed out the rear of the shell. If the insulator is displaced with this test, please repeat steps 1 and 2. Step 4: Complete assembly by adding coupling nut and endbell. Please note that the coupling nut is used on the plug side only. *Note: During installation, ensure that all contacts remain fixed. If during this process the contacts rotate out of position, separate the 2 piece insulator and adjust accordingly.
