Industrial SF4B-H16 Light Curtain Sensor Emitter

SunX SF4B-H16 light curtain emitter is a Type 4 safety device that creates the protective field of a safety light curtain when paired with SF4B receivers. It features 16 beam channels at a 20 mm pitch, delivering a protective height of 343.4 mm (13.52 in) and a sensing range of 0.3 to 9 m. This emitter is used for machine guarding on presses and automated lines, and it belongs to Panasonic's SUNX SF4B family known for compact form and compatibility with corresponding receivers. In pigtailed configurations it draws about 65 mA or less at 24 V DC and weighs roughly 360 g; cable-type variants are heavier, around 700 g. The minimum detectable object diameter is 25 mm (0.98 in), and the system supports Type 4 protection with the appropriate receiver, enabling reliable stop functions in industrial automation.
