SEC900 ESD Access Control Turnstile by Southern Machinery

What is the SEC900 used for? The SEC900 is an ESD access control system that tests the static carried by personnel before they enter an ESD-protected area. It combines a human-body static tester, access gates and management software so only people who passed the required test get through.

Why do ESD checks still fail in so many factories?

The usual weak point is not the wrist strap. It is the person who skips the check. The source describes traditional anti-static testing as manual recording or rough checks: time-consuming and prone to missed tests through human error, which creates quality risk for sensitive components.

If you run an EMS, automotive or medical electronics floor, you probably recognize it. The policy exists on paper, but nobody can prove who was tested this morning.

How do you make the test impossible to skip?

Use a simple four-step model:

1. Define the test per role. Wrist strap only, shoes only, hand and shoes together, or exemption.
2. Bind the test to the door. The gate opens only after the result is accepted.
3. Record every event. Name, ID, photo, department, time, channel, test item and measured value.
4. Review exceptions weekly. Filter for people who should have been tested but were not.

The source says the system's mandatory settings and targeted testing remove human factors, making results more reliable and credible.

What does the SEC900 actually include?

The system consists of WEB ESD management software, an ESD cloud controller, a 7-inch display screen, an electrostatic tester, a dual shoe test plate, a recognition module (face recognition, fingerprint or card reader, individually or combined) and a turnstile gate.

Which gate type fits your entrance?

| Type | Chassis size (customizable) | Notes from source |

|---|---|---|

| ESD-Tripod Turnstile | L1200 x W280 x H980 mm | 600 mm passage; arm drops on power failure |

| ESD-Flap Barrier | L1200 x W300 x H980 mm | Opens automatically on power failure |

| ESD-Swing Gate | L1200 x W280 x H980 mm | Opens automatically on power failure |

| ESD-Wall-Mounted | L440 x W270 x H75 mm | 7-inch display, card/fingerprint/face optional |

| ESD-Barrier-Free Access | L320 x W280 x H1000 mm | Go/No Go indicator |

| ESD-Speed Gate | L1400 x W140 x H1000 mm | 10-inch display; opens on power failure |

| ESD-Bracket Style | Customizable | Offline only; door open signal output |

Most gate types are bidirectional (entry and exit) and run offline or networked over TCP/IP.

What can the electrostatic tester measure?

• Standards: GJB 3007-97, SJ/T 10694 and ANSI ESD S20.20 (as listed in the source).
• Test modes: single-wire wrist strap, double-wire wrist strap, electrostatic dual shoes.
• Wrist strap limits: lower 100K or 750K ohm; upper 10M or 35M ohm.
• ESD shoe limits: lower 100K, 300K, 500K, 750K ohm; upper 35M, 100M, 500M, 1000M ohm.
• Overall error: plus or minus 5%.
• Operating temperature: -10 to +60 C. Power: AC-coupled adapter (8-12 VDC).
• Resistance limits can be adjusted by software or DIP switch, with no return to factory.
• The dual shoe plate is sealed and waterproof, with shielded cable, and distinguishes left from right shoe.

How does the software reduce admin work?

The management software sets test authority per person, controls which doors each role may use and when, and supports holiday and time-zone control. It also offers a one-time test for all-day access, anti-passback, personnel counting with a limit alert, camera snapshots at the gate, and report filtering by pass rate. One software suite can manage hundreds of devices, and any LAN computer can use it through a browser.

How do you fit it into a PCB assembly plant?

Place the gate at the entrance to the SMT and THT production zone, then keep the same discipline along the line. Southern Machinery supplies complete SMT and THT lines plus board handling and inspection, so ESD control can be planned together with the line layout. See our THT machine range, board handling systems and 3D SPI and AOI equipment.

What is the return on an ESD gate?

Use this formula as a planning example only:

Annual value = (avoided ESD-related rework + saved manual logging hours) - annual running cost

Every input depends on configuration and your own plant data. Prices, rework rates and labor cost are not specified in source - contact Southern Machinery to confirm. Any result is an example, subject to final technical confirmation.

What should you do next?

Count your ESD entrances and decide which test each role needs. Then pick a gate type from the table. Southern Machinery was founded in 2011 in Shenzhen and serves 237+ global customers. The source lists 7x24 worldwide support, free installation and training, 1 day lead-time for spare parts and a 1 month customized solution.

FAQ

Which standards does the tester reference? GJB 3007-97, SJ/T 10694 and ANSI ESD S20.20, per the source.

Can it work without a network? Yes. Gates run offline or networked via TCP/IP; the bracket style is offline only.

What happens in a power failure? The tripod arm drops; flap and swing gates open automatically, for evacuation.

Can we customize it? The source lists customization of size, style, software functions, tester parameters, display pages and third-party interfaces.

Which recognition methods are supported? Card, fingerprint or face recognition, selectable individually or combined.

Can it test different people differently? Yes. Authority can be set per person: wrist strap, shoes, both, or exempt.
