Keyence SL-V79F-R Light Curtain Receiver Unit

Keyence SL-V79F-R Light Curtain Receiver Unit is the receiving element of a safety light curtain system designed for industrial use. It operates on 24 VDC and delivers a rapid 16.8 ms detection response, enabling quick recognition of beam interruptions. With a detection zone of 790 mm, the unit defines the protective field that guards personnel and equipment in production lines and automated environments. This receiver is a dedicated component of Keyence safety hardware, built to monitor the protective field and signaling when a beam is broken. The exact specifications—24 VDC input, 16.8 ms response time, and a 790 mm detection range—provide the concrete criteria engineers need to determine compatibility with guarding requirements in compact to mid‑sized automation setups.
