Precision 50mil, 75mil, and 100mil spring probe pogo pins designed for PCBA testing, featuring 0-50A current rating and reliable 50m$\Omega$ contact resistance.

High-performance probe pin socket featuring a Rh-plated BeCu plunger and gold-plated brass barrel, designed for reliable electronic testing and PCB socket applications.

Featuring an internal thread design and high-durability spring mechanism, the SF-GP6.0*50 test probe pin connector delivers reliable electrical contact and precise mechanical stability for industrial testing fixtures.

Featuring a precision spring-loaded design and durable construction, this industrial PCB guide pin ensures accurate alignment, smooth stabilization, and reliable mechanical positioning for electronic testing fixtures.

The SF55-6-23-180A is a heavy-duty high-current test clamp featuring a Beryllium Copper (BeCu) conductor sheet, PPS1140 insulating housing, and functional gold plating rated for up to 180A continuous current and a lifespan $\ge$ 30,000 cycles.

The SF30-5-23-60A soft pack battery clip features durable brass construction with Au plating over nickel, engineered to deliver stable 60A high-current transmission for battery testing and electronic interconnect applications.

Featuring a 1.27mm recommended minimum center, SK4 Ni/Au plated plungers, and stainless steel springs, this high-quality gold-plated PCB spring test probe pin is engineered for gentle, non-destructive contact on PCB gold fingers, pads, and ICT test fixtures.

SFENG spring‑loaded guide pins are precision positioning parts for PCB ICT & FCT test fixtures. Made of brass housing with nickel‑plated finish and stainless‑steel spring, they accurately align PCBs, avoid board offset and protect test probes during mass testing.

SFENG screw-in test probes deliver reliable electrical contact, outstanding durability, and anti-loosening precision through high-quality gold-plated brass/beryllium copper construction—providing a cost-effective testing solution for PCB and electronic component inspection.

Factory‑direct 3A ICT switch probe is normally‑open spring‑loaded switch pin for ICT/FCT test fixtures. It triggers circuit closing at designated travel to detect PCB or component presence, rated 3A current with gold‑plated contact for low contact resistance. PEEK insulating sleeve ensures reliable insulation. Standard sizes in stock, custom switching travel, spring force and length available. RoHS & ISO9001 compliant, samples for evaluation are offered.
