Product Selection

1.  Safety Light Curtain—Standard System

The Allen-Bradley Guardmaster GuardShield Safe 4 safety light curtains are offered in 14 mm and 30 mm resolutions, are ordered as pairs—transmitter and receiver—and are shipped under one catalog number. Each GuardShield Safe 4 pair is shipped with mounting brackets. After selecting the appropriate Safe 4 protected height and resolution, ensure that the appropriate cord sets, interfaces, and accessories are ordered as well.

Note:The cat. nos. listed above are pair cat. nos., to specify a transmitter or receiver only, substitute the P in the cat. no. with a T for transmitter or an R for receiver.

2.  Cordsets—Transmitters and receivers both use 5-pin M12 cordsets

Note: Unshielded cordsets are most commonly used for safety light curtains, however, shielded cordsets are also offered to increase immunity to electrical interference.
