Sync Cable Yongnuo LS-PC635 PC jack to 3.5mm mini jack flash sync cable

The Yongnuo LS-PC635 sync cable connects a camera or trigger device with a PC (Prontor/PC) plug to a flash unit or strobe that accepts a 3.5 mm mini jack. It provides a reliable wired connection for synchronous flash firing where hotshoe or wireless triggering is unavailable or not preferred. The cable is intended for studio and on-location photography workflows that require predictable timing and electrical compatibility between camera and lighting equipment.

Advantages

The cable offers a straightforward physical connection that minimizes latency and avoids interference common with some wireless systems. Its simple construction supports direct triggering without configuration or batteries, and the standard PC and 3.5 mm connectors ensure broad compatibility with many flashes, strobes, sync ports and remote triggers. The cable is lightweight and easy to route in a studio or on-location setup.

Suitable for

• Studio photography with monolights or strobes that provide a PC or 3.5 mm sync port
• On-location shoots where wireless triggering is restricted or unreliable
• Remote flash units or older camera models lacking an on-camera hotshoe trigger
• Photographers seeking a simple wired sync solution for consistent timing

Key specifications

• Connector A: PC (Prontor/PC) plug for camera or trigger connection
• Connector B: 3.5 mm mini jack for flash or remote trigger input
• Function: Wired flash sync for firing external strobes and flashes
• Construction: Insulated cable with molded connector ends for secure fit
• Compatibility: Designed to work with devices that accept PC and 3.5 mm sync connections

How to use

Attach the PC plug to the camera’s or trigger’s PC terminal and insert the 3.5 mm mini jack into the flash or strobe’s sync port. Verify that both devices are powered on and set to compatible sync modes. Conduct a test shot to confirm the timing and exposure. Route the cable to avoid strain on connectors and keep it clear of moving parts or subjects. Disconnect the cable by gently removing the connectors—do not pull on the cable jacket.

Usage recommendations

Use the LS-PC635 cable in situations that require consistent wired triggering. Inspect connectors periodically for dirt or wear and ensure secure connections before shooting. Avoid bending the cable sharply near the connector ends and keep the cable dry and free from heavy mechanical stress.
