Yes. A PC sync connection is a simple, cross-brand trigger connection, so a camera and flash with compatible PC sync ports can generally be connected regardless of manufacturer.

However, PC sync only sends the basic fire signal. It does not carry brand-specific TTL, exposure, or feature communication, so you should expect to use the flash in manual mode. As long as both devices have PC sync and the flash can be fired that way, it should work for a setup like self-portraits.
