The fiber optic sensors use a small, sealed fiber optic cable to view the target while the sensor is mounted in a remote or more convenient location. This provides greater durability and flexibility with sensor installations that involve confined spaces or severe environments. The fiber cables can range in length from 3 to 30 feet (1-9 m). Some unique fiber optic accessories include:

• ArmorGuard (AG) System - A heavy duty, flexible, stainless steel armored fiber optic cable conduit with two layers of insulation and an air purge for maximum protection against flame impingement and high ambient temperatures.
• Stainless Steel Braid System (SSB) - A flexible, lightweight fiber optic cable conduit with a durable inner Teflon sleeve and an air purge for general-purpose protection in industrial installations.
• Gooseneck System (GN) - A 3 ft (90 cm) semi-rigid fiber optic cable conduit (with an air purge) that allows quick and easy alignment adjustment.
