Cable lengths up to 60m (196.8ft) are permitted (over-voltage protection for level 3 and higher (IEC 801), see Technical Data). The transmitter is connected to a 24V supply using a 7-conductor cable. The receiver is connected to the machine control and 24V supply using a 7-conductor cable. The maximum wire cross section is 1.5mm (0.06in) without jacket; 1mm (0.04in) with jacket. All light curtains come standard with prewired mini style quick-disconnect connectors in the end-caps. The POC requires +24V DC (± 20%) power supply, which is available from Allen-Bradley Guardmaster.

If an external test is desired, a contact (normally closed) can be connected at the test input (MCC = Machine Control Contact). Minimum opening duration ≥50ms. Continuous current during closed test input: 12mA. In-rush current when closing: 150mA (20ms). Test input open = Testing = Outputs on receiver inactive (red).
