What are the key features of TOLC-125-12-L-Q-A?
- Quad-row (FOURRAY) staggered contact pattern on 3.175mm (.125") pitch maximizing contact density in a compact 1.35 inch body length
- 10 µin gold over 50 µin nickel contact finish providing low contact resistance and superior corrosion resistance for long-life interconnects
- Phosphor bronze contact material delivering excellent spring-back and retention force for reliable mating across thousands of insertion cycles
What is TOLC-125-12-L-Q-A used for?
TOLC-125-12-L-Q-A is designed for high-density board-to-board and board-to-cable interconnect applications in test equipment, industrial automation, and defense electronics where a quad-row connector maximizes signal count within a limited PCB footprint. The gold-plated phosphor bronze contacts ensure reliable electrical performance in low-level signal and high-cycle mating environments, making this connector suitable for rack-and-panel systems and backplane interconnects requiring stable contact resistance below 20 mΩ.

Frequently Asked Questions
What contact finish is used on TOLC-125-12-L-Q-A and how does it affect contact resistance?
TOLC-125-12-L-Q-A uses 10 µin gold plating over 50 µin nickel on its phosphor bronze contacts. This gold finish provides a contact resistance typically below 20 mΩ and excellent resistance to oxidation and fretting corrosion, making the connector suitable for low-level signal applications and environments with thermal cycling that could degrade base metal contacts.
How many contact positions does TOLC-125-12-L-Q-A accommodate given its quad-row FOURRAY configuration?
With 12 positions across 4 rows in the FOURRAY configuration, TOLC-125-12-L-Q-A provides 48 total contact positions within a 1.35 inch body length on a 3.175 mm (.125 inch) pitch. This high contact density allows routing of 48 signals or mixed power/signal combinations through a single compact connector footprint.
In which board interconnect scenarios does the staggered contact pattern of TOLC-125-12-L-Q-A offer a layout advantage?
The staggered contact pattern spaces adjacent contacts offset from one another, reducing crosstalk and improving signal isolation between neighboring pins at data rates above 100 MHz. This layout benefit makes TOLC-125-12-L-Q-A well suited for backplane connectors, high-speed digital I/O headers, and FPGA daughter-card interfaces where simultaneous switching of many 3.3 V or 5 V signals would cause excessive noise on a non-staggered connector.
