What 1 2606291u201q1 Is and Why It Holds Tight Tolerances 1 2606291u201q1 is a stamped terminal/contact blank produced on 25-ton high-speed Bruderer presses at our Dongguan factory. You get a flatne
1 2606291u201q1 is a stamped terminal/contact blank produced on 25-ton high-speed Bruderer presses at our Dongguan factory. You get a flatness of 0.02 mm over the entire contact surface, a burr height under 0.03 mm, and a hardness range of 38–42 HRC after selective heat treatment. This part is made in China, but it meets IPC-2221B and automotive-grade dimensional standards. We ship it with a 100% first-article inspection report, and typical lead time is 7 working days from drawing approval.
Our progressive dies for 1 2606291u201q1 use D2 steel with a mirror-polished cavity finish (Ra 0.2 µm). That means each stroke produces a terminal with zero die rollover on the critical mating edge. We add a micro-straightening station in the die to correct any springback after forming. The result: the contact point stays within ±0.01 mm of true position, even after 500,000 strokes without die maintenance.
You can order 1 2606291u201q1 in C5191 phosphor bronze, C17200 beryllium copper, or 304 stainless steel. For high-cycle connectors, we recommend the beryllium copper version with a 0.4 µm gold flash over nickel underplate. That gives you contact resistance below 10 mΩ and a lifespan of 10,000 mating cycles. If you need a cost-effective option, phosphor bronze with tin plating works up to 150°C continuous.

For 1 2606291u201q1, we use vacuum hardening to avoid surface oxidation. The tempering cycle is controlled to keep hardness at 40 ± 2 HRC without making the part brittle. Plating options include selective gold (only on the contact tip), full tin, or silver. Each batch gets a cross-section test for plating thickness—we measure at 5 points, not just the center. The plating adhesion is checked with a tape test per ASTM B571.
Every single 1 2606291u201q1 piece passes through a Keyence CV-X400 optical sorter. It checks for burrs, dents, bends, and plating defects at 400 parts per minute. In addition, we pull 5 pieces per lot for a CMM measurement of all critical dimensions. You receive the full inspection report with the shipment, including the raw material certificate. If you need PPAP Level 3, we can do that too—just note it on your RFQ.
We ship 1 2606291u201q1 in anti-static trays or tape-and-reel, depending on your assembly line. For tape-and-reel, the pocket depth is matched to the terminal height so parts do not wobble during high-speed placement. Each reel is sealed in a vacuum bag with desiccant and humidity indicator. For loose parts, we use partitioned boxes with ESD foam—no random tumbling in a plastic bag.
Stamping 1 2606291u201q1 costs 60–70% less than CNC machining the same geometry. The cycle time per part is 0.08 seconds, versus 2 minutes for a milled version. Stamping also gives you a consistent grain flow that improves fatigue resistance in bending applications. For prototype volumes under 100 pieces, CNC machining is faster to get parts in hand—see our stamping vs CNC prototype guide for the crossover point.
If you need to increase the current carry capacity of 1 2606291u201q1, we adjust the die clearance from 5% to 8% of material thickness. This changes the shear zone ratio and reduces contact resistance at the mating surface. We simulate this in AutoForm before cutting steel, so you get the exact performance you need without trial-and-error. For help with material selection, read our CNC cutting tool selection guide.
For 1 2606291u201q1, we recommend either selective gold plating or a bright acid tin finish. Gold gives the lowest contact resistance and is best for signal contacts. Tin is cheaper and works for power terminals up to 10 A. If you need a matte finish to reduce reflection in optical sensors, we can electropolish the surface. More details are in our stamping finishing options guide.
No MOQ means you can order 5 pieces of 1 2606291u201q1 for a test fit. We charge a small tooling fee for the first order, but that fee is fully credited back once your cumulative order reaches 10,000 pieces. For prototypes, we use a soft die that is ready in 3 days. Once you approve the sample, we switch to the production die—no extra cost for the rework.
There is no minimum order—you can order a single piece for validation, and the unit price stays the same as for 1,000 pieces.
Yes, we adjust gold plating from 0.1 µm to 0.8 µm and tin from 2 µm to 8 µm, based on your current rating and environmental test requirements.
We use SPC on every 1,000-piece batch, monitor the press tonnage in real-time, and do a 100% optical inspection before packing—a defective part cannot leave the line.
For a minor modification to the existing die, we can ship samples in 5 days and production parts in 10 days; for a brand-new die, add 3 weeks for tooling.
