The MS4320B-2 variant operates on 115 VAC at 50\/60 Hz and draws about 0.25 A, with a response time under 35 ms to detect beam interruptions quickly. Manufactured in the United States, this 20-inch (0.51 m) module is sold individually and represents the standard Minisafe-B receiver form factor used in STI beam-curtain configurations. As part of a complete safety-light-curtain setup, it is paired with a corresponding transmitter to monitor access openings and trigger protective actions when a beam is broken. The compact, long 20-inch design and straightforward electrical requirements make it suitable for guarding medium-length machine perimeters in automated environments, including booths and presses, where rapid detection of intrusion is critical.\u003c\/p\u003e\u003c\/div\u003e","brand":"STI","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46253658013930,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-011.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-ms4320b-light-curtain-receiver-transmitter-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
