Safety System Replaces Interlock Switches

Offered as a replacement for safety interlock switches used to safeguard potentially dangerous machines, the PICO-GUARD fiber optic safety system is a combination of non-contacting photoelectric and fiber optic technologies. It consists of a controller, an array of optical interlock switches, and plastic fiber-optic cable to monitor doors, gates, and hard guards. The controller portion provides four independent optical channels. Each channel can control multiple safety-lock switches in the same optical network. Additional interlock switches can be added to any channel by inserting them into the fiber-optic loop for that channel. The system’s receiver provides two solid-state outputs that control 24 Vdc loads. In addition, the system meets ISO 13849-1 Category 4 requirements.
