Safety is worth more than just two points for Scientific Technologies Incorporated (STI). The company's Safety Automation Products Group makes safety light guards, safety interlocks and relays, safety mats, and controllers used to safeguard personnel in manufacturing environments near robots and moving machinery. The smaller Automation Products Group makes photoelectric and fiber-optic sensors, ultrasonic sensors, optical profiling scanners, power-monitoring and defense electronics, microcomputers, and peripherals for controlling automated industrial processes. STI is 86% owned by Scientific Technology Incorporated, which is owned by chairman Anthony Lazzara and his family.
