W2SA is a wedgelock designed for DT Series 2-way plug connectors, specifically configured with an A-key keying system. This wedgelock is used to secure and align the plug connector during mating operations, ensuring proper contact retention and alignment. The gray color coding corresponds to the A-key configuration, allowing for keyed mating to prevent incorrect connector pairing. W2SA is commonly used in automotive and industrial applications where reliable connector locking and alignment are critical for maintaining electrical integrity in harsh environments.
