Sunx SF1S-16P Fiber Optic Safety Photoelectric Sensor

Sunx SF1-S16P fiber optic safety photoelectric sensor is a 16-beam, 20 mm beam-pitch high-functional area sensor in the SF1-S Series, designed to form a safety field along a machine access point by distributing detection across multiple fiber-optic beams rather than a single point. This architecture supports reliable access guarding in demanding environments and is typically used with fiber emitters and receivers to cover extended protection zones. The SF1-S16P operates from a 24 V DC supply with ±10% tolerance and features a warm-up time of 500 ms or less to reach stable operation. The enclosure is ABS, with a PBT terminal block containing glass-fiber reinforcement and a polycarbonate protective cover, reflecting Sunx’s rugged construction for industrial safety sensors. For the SF1-S16 family, the documented footprint is about 300 mm wide by 332 mm high by 349 mm deep, aligning with the 16-beam configuration. This sensor sits within Sunx’s safety sensor lineup, including variants that incorporate enhanced safety circuitry to monitor system integrity and implement lockout behavior in critical applications. Typical uses include guarding machine access on conveyors and automated lines where a multi-beam optical field provides reliable intrusion detection without imposing bulky hardware.
