Product Information

Full details

The Cliff FCR1215 is a professional-grade 6.35mm stereo jack socket designed for engineers and hobbyists seeking a high-density, reliable audio connectivity solution for PCB projects. It delivers exceptional durability through self-cleaning contacts and a rugged construction, making it ideal for rack-mount gear or dense circuit designs; however, users should ensure their PCB layout accounts for the specific kinked leg footprint to ensure a secure mechanical fit.

Extended Product Information

FAQs

What is the maximum current rating for this jack?

The FCR1215 is rated for a maximum current of 5A.

Does this socket support balanced audio signals?

Yes, as a stereo jack with three contacts, it can be used for balanced mono signals (Tip, Ring, Sleeve) or standard stereo signals.

Can this be used in extreme temperatures?

It is rated for operation between -10°C and +70°C, which covers most indoor and pro-audio environments.

What does the 'kinked leg' design do?

The kinked legs provide mechanical retention to hold the component in place on the PCB before the soldering process is completed.

Is the mounting nut included?

Yes, the FCR1215 is supplied with a mounting nut for secure chassis attachment.

How many insertion cycles is this rated for?

It has a minimum operational life of 10,000 cycles.

Troubleshooting

Intermittent audio signal

Check the solder joints on the PCB to ensure the kinked legs are fully seated and that the ground connection is continuous.

Socket feels loose when plugging in cables

Verify that the mounting nut is tightened correctly to the panel and that the PCB itself is securely mounted within the enclosure.

Signal does not break when cable is inserted

Inspect the breaking contacts to ensure no debris is preventing the internal switches from opening as the jack is inserted.

Pros and Cons

Pros

  • High operational lifespan of 10,000 cycles
  • Secure PCB mounting via kinked legs
  • Excellent signal integrity due to low-noise contact design
  • Wide operating temperature range (-10°C to +70°C)
  • Includes mounting nut for chassis-integrated security

Cons

  • Requires specific PCB footprint for kinked legs
  • Primarily for internal PCB-mount use, requiring chassis modification for external access
  • Not intended for non-stereo applications without bridge wiring

Setup, Compatibility & Care

Installation

  1. Ensure your PCB drill pattern aligns with the FCR1215 pin configuration, noting the kinked leg placement for retention.
  2. Insert the jack into the board and solder the contact pins.
  3. Secure the socket to the front panel using the included mounting nut to prevent mechanical stress on the PCB solder joints during frequent cable insertions.

Care and Maintenance

  • To maintain the longevity of the self-cleaning contacts, avoid introducing debris or moisture into the socket.
  • If the device is used in a high-dust environment, occasionally using a specialized contact cleaner designed for electrical components can help maintain the low-noise characteristics.
