MLC511R30-450.1 — technical product overview
MLC511R30-450.1 (68025304) is a safety light curtain receiver for projects assessed around a 450 mm nominal protective field. Its 30 mm resolution and 9 ms receiver response are distinct selection parameters, not a complete stopping-time specification.
This MLC511.1 variant has two PNP OSSDs, a 24 V DC ±20% supply and a four-pin M12 male connector. Its Basic package includes DoubleScan, automatic start/restart and transmission channel selection. A five-pin MLC510 receiver cable must not be assumed to have the same pin assignment; integration requires the diagram for the exact model.
The 450 mm nominal field is not the overall device height; this receiver has a mechanical height of 516 mm. Connector clearance, optical alignment and access around the protected opening belong in the same installation review.
The 30 mm resolution is relevant to a hand-protection assessment. Layouts that allow someone to remain behind the field may require additional measures.
Include the safety-controller 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.

Frequently asked questions
Is MLC511R30-450.1 a transmitter-receiver kit?
No. Order code 68025304 specifies the receiver only. Select a compatible transmitter and connection accessories separately.
Is 450 mm the overall body height?
No. The nominal field is 450 mm; the mechanical height is 516 mm, excluding installation clearance.
How is MLC511R30-450.1 connected?
It uses 2 PNP OSSD with a 4-pin M12 male connector. Supply: 24 V DC ±20%. Check the exact-model pin assignment before connection.
Does 9 ms describe the complete stopping time?
No. It is the receiver response. Add controller/network delays and the measured stopping time of the machine.
