Printed in USA

interfaced with a PICO-GUARD Fiber Optic

Controller to be considered a safeguard. See

the PICO-GUARD Controller Instruction

Manual (p/n 69761) and the PICO-GUARD

Application and Design Guide (p/n 69763) for

complete installation instructions,

maintenance instructions, and application

limitations.

Use of a Banner PICO-GUARD Fiber Optic

Safety Interlock Switch is generally not

allowed for:

Follow all installation and maintenance

instructions with extreme care. The user is

responsible for following all local, state, and

national laws, rules, codes, and regulations

relating to the use of this safeguarding

system in any particular application.

• Establishing a beam for presence-sensing

• Linear (parallel) movement along the

• Machinery with long stopping time and

safeguarding (e.g., perimeter guarding),

optical axis (see Figure 2 and the

Application and Design Guide), or

without a guard-locking mechanism.

Warning ...

Misapplication of this Product

PICO-GUARD optical elements

must be properly installed and

Avoid

• Compact, non-contact, easy-to-install means of interlocking doors, guards, gates, and covers

• U-shaped configuration lallows fiber to “enter” and “exit” from one side of the guard only

• Simple, quick means of connecting and disconnecting the fiber

• For use with Banner 2.2 mm OD plastic fiber optic cable (1 mm core)

• Actuator available with PVC or fluoropolymer-sheathed fiber loop (XP or XT models)

• Designed to meet Safety Category 4 applications with one switch pair per guard (per ISO13849-1)

• Impact-resistant polycarbonate plastic construction

• Environmental rating of IEC IP67

• Attenuator available (see p/n 109910) for reducing excess gain in short-run applications

• Splice available for easy connection of two fiber sections (see p/n 109910)
