LFS-652
Personnel ESD testing for wrist straps, footwear and grounding garments, with turnstile and face-access-control integration options.
View specifications →ESD TURNSTILE & ACCESS CONTROL
ESD turnstile and personnel access-control configurations
For electronics manufacturing, SMT, cleanrooms and laboratory entrances, combine a personnel ESD tester with face recognition, card access, turnstiles and ESD entry/exit records.
Standalone tester
For workstations, entrances or small facilities. A passed test can trigger a relay to control a lock, indicator, buzzer or turnstile.
Display-screen version
For sites that need a clear visual result. LFS-619 documentation covers a 3.5-inch resistance display; LFS-650 and LFS-652 documentation covers an 8-inch serial-screen mode.
Face-recognition access control
Combine a tester with a 7-inch binocular face terminal for identity verification, ESD testing, access control and event records.
Face-access-control integration
This full wiring diagram shows an LFS-619 tester with a face terminal, access-control board, card reader and RS-485 connection. Final wiring and interfaces are confirmed by the supplied version and project documentation.

FACE RECOGNITION ESD TERMINAL
7-inch binocular face-recognition ESD terminal
This terminal can be combined with an LFS tester for online/offline face recognition, card recognition, ESD test control, access control and event records. It can also perform ESD testing without face or card verification when the workflow requires it.
Key advantage: two-way ESD access control
Entry direction: personnel verify by face recognition or card, complete the ESD test, and the turnstile opens after a passed result. Exit direction: card presentation opens the turnstile for exit. Unlike common face-access workflows limited to one direction, this system supports managed entry and exit in both directions.
- Binocular wide-dynamic-range cameras with liveness detection; source material states recognition from 0.3 seconds and up to 2 m distance.
- Offline face enrolment without mandatory backend or cloud; supports 1:N face, 1:1 ID verification and optional IC/ID cards.
- 20,000-person list capacity, expandable to 50,000; 200,000 records; optional IC/ID reader.
- Per-person modes include wrist test, footwear test, full test and VIP; ESD test ranges can be set in software.
