MLC510R40-1500.1 — technical product overview
Selecting Leuze MLC510R40-1500.1 starts with the relationship between its 1500 mm nominal field and 40 mm resolution. The 28 ms response assigned to order code 68026415 concerns the receiver, not the complete machine safety loop.
The MLC510.1 version uses a 24 V DC ±20% supply, two PNP OSSDs and a five-pin M12 male machine connector. The Basic package provides DoubleScan, automatic start/restart and transmission channel selection. Its response must not be copied from a standard MLC510 without the .1 suffix; use the 28 ms value assigned to this exact model.
The 1500 mm nominal field is not the overall device height; this receiver has a mechanical height of 1566 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 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 MLC510R40-1500.1 a transmitter-receiver kit?
No. Order code 68026415 specifies the receiver only. Select a compatible transmitter and connection accessories separately.
Is 1500 mm the overall body height?
No. The nominal field is 1500 mm; the mechanical height is 1566 mm, excluding installation clearance.
How is MLC510R40-1500.1 connected?
It uses 2 PNP OSSD with a 5-pin M12 male connector. Supply: 24 V DC ±20%. Check the exact-model pin assignment before connection.
Does 28 ms describe the complete stopping time?
No. It is the receiver response. Add controller/network delays and the measured stopping time of the machine.
