SC350 350A 600V Forklift Battery Connector, T2 Silver-Plated Contacts, PC110U IP20

• SC50: Compatible with 10/12 AWG, 8 AWG, and 6 AWG cables.
• SC175: Supports 4 AWG, 2 AWG, 1 AWG, and 0/1 AWG cables.
• SC350: Designed for 2/0 AWG, 3/0 AWG, 4/0 AWG, and 300 AWG cables, accommodating a wide range of heavy-duty wiring needs in high-power applications.

Reading Temperature Rise in Service

A connector that runs warm is telling you something. On a 350A lead, a rise of a few degrees above the surrounding cable usually points at a loose ferrule rather than the contact itself, while a hot plug body after a short charge often means the mating halves are not fully seated.

Maintenance teams can use that as a simple field check: feel the plug after a charge cycle, compare left and right leads, and log anything that stands out. Because the SC350 keeps contact pressure steady, a plug that starts to run hotter than its neighbours on the same charger is a signal to inspect the cable termination before replacing the connector.

When a Connector Should Be Retired

Silver-plated contacts do not fail suddenly. They give warning through heat, discoloration at the contact face and a mating action that no longer feels firm. Retiring a plug at that point costs far less than a melted housing on a truck mid-shift.

Keeping one spare SC350 kit on the shelf, with its handle and cover, means a worn unit can be swapped out during the same shift it is spotted, and the old one can be inspected at leisure rather than under pressure.

Low-Resistance T2 Silver-Plated Contacts for Stable Power Transfer

At 350A the contact quality decides how much power actually reaches the truck. The SC350 uses T2 silver-plated contacts that resist oxidation and keep contact resistance low, so current flows efficiently and the connector runs cooler over thousands of mating cycles.

• T2 silver-plated contacts resist oxidation and corrosion
• 2500V DC dielectric strength and IP20 protection
• Rated 350A / 600V for continuous high-current service

Frequently asked about this connector

Q: Why does the SC350 use silver-plated contacts?

A: Silver plating resists oxidation and keeps contact resistance low, supporting efficient current transfer and a longer, more reliable service life.

Q: What protects the connector in a dusty workshop?

A: The connector is rated IP20 to keep out solid objects, and the supplied cover adds further protection when the plug is not in use.

Quality Control at the Contact Face

Every SC350 lot is judged by what happens where the current crosses, not by how the housing looks on the shelf. Each production batch is sampled for contact resistance and temperature rise under a 350A load before release, and the readings are filed against the lot number so a truck fleet can be traced back to the run it came from.

Production follows ISO9001 and ISO/TS16949 procedures. Incoming PC110U resin is checked for grade and flow, moulded shells are inspected for flash and wall thickness, and T2 silver plating is verified on coupons rather than assumed from the supplier certificate.

Finished plugs receive a 100% electrical pass test, and units outside the resistance window are scrapped instead of reworked, because a reworked contact face is exactly where heat starts. Certifications are held across UL, TUV, CE, CSA, SAA, PSE, NF and BS so the same connector can be shipped into most major markets with its paperwork intact.

Stock units leave in three to five working days; tailored builds follow in five to seven days after the T/T payment lands. Samples can be produced to your drawing before volume, private-label marking is supported, and every shipment carries routine test records for your own quality file.

• Lot-level contact resistance and temperature rise records

Application Scenarios

The SC350 is built for daily battery charging and swapping, where a reliable, low-resistance connection keeps fleets moving.

• Electric forklifts & warehouse trucks: continuous 350A battery leads with silver-plated contacts for stable power transfer.
• Stackers & reach trucks: compact plug bodies that fit tight battery compartments and speed up battery changes.
• AGVs & automated warehousing: repeatable, self-aligning connection for automated battery swapping and charging.
• Charging & battery rooms: charger-to-battery connections with IP20 protection and acid-resistant housing.
