Note: The GuardShield transmitter requires a 4-pin cable and the receiver requires an 8-pin cable.
Recommended Logic Interfaces
The Allen-Bradley Guardmaster GuardShield safety light curtains are ordered as pairs—transmitter and receiver—and are shipped under one
part number. Each GuardShield Type 2 transmitter and receiver is packaged with two right angle mounting brackets. After selecting the
appropriate light curtain pair, ensure that required interfaces and accessories are ordered.
