MLC510R40-225/A — technical product overview
MLC510R40-225/A (68007402) is a safety light curtain receiver for projects assessed around a 225 mm nominal protective field. Its 40 mm resolution and 3 ms receiver response are distinct selection parameters, not a complete stopping-time specification.
The /A variant connects to AS-Interface Safety at Work and is supplied at 26.5–31.6 V DC from the AS-i circuit. It uses a five-pin M12 male connector. Safety information is transferred as a safe AS-i code sequence; this is not the wiring arrangement of a conventional two-PNP-OSSD receiver. Addressing, the safety monitor and the network configuration must be checked together.
The 225 mm nominal field is not the overall device height; this receiver has a mechanical height of 291 mm. Connector clearance, optical alignment and access around the protected opening belong in the same installation review.
A 40 mm resolution does not provide the same detection capability as a fine-resolution finger-protection model. The access scenario needs its own assessment.
Include the AS-i cycle and safety-monitor delay when calculating total response together with measured machine stopping time. The Type 4 / PL e / SIL 3 device classification does not by itself establish compliance of the complete machine. This record is for the receiver only; a compatible transmitter is selected separately.

Selection and commissioning
Use the exact-model wiring diagram, isolate energy before work, and have a competent person validate both the protection function and the restart behavior. Verify the required safety distance with the actual machine stopping time.
Frequently asked questions
Is MLC510R40-225/A a transmitter-receiver kit?
No. Order code 68007402 specifies the receiver only. Select a compatible transmitter and connection accessories separately.
Is 225 mm the overall body height?
No. The nominal field is 225 mm; the mechanical height is 291 mm, excluding installation clearance.
How is MLC510R40-225/A connected?
It uses AS-Interface Safety at Work with a 5-pin M12 male connector. Supply: 26.5–31.6 V DC from the AS-i circuit. Check the exact-model pin assignment before connection.
Does 3 ms describe the complete stopping time?
No. It is the receiver response. Add controller/network delays and the measured stopping time of the machine.
