MLC510R40-1050/A — technical product overview
Selecting Leuze MLC510R40-1050/A starts with the relationship between its 1050 mm nominal field and 40 mm resolution. The 10 ms response assigned to order code 68007410 concerns the receiver, not the complete machine safety loop.
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.
Use the 29 × 1116 × 35.4 mm housing dimensions for mechanical layout. The 1050 mm nominal field and overall body height are different; allow additional clearance for mounting and the connector.
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 MLC510R40-1050/A a transmitter-receiver kit?
No. Order code 68007410 specifies the receiver only. Select a compatible transmitter and connection accessories separately.
Is 1050 mm the overall body height?
No. The nominal field is 1050 mm; the mechanical height is 1116 mm, excluding installation clearance.
How is MLC510R40-1050/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 10 ms describe the complete stopping time?
No. It is the receiver response. Add controller/network delays and the measured stopping time of the machine.
Automation engineering support
For MLC510R40-1050/A (68007410), specify quantity, access geometry, required safety level and control interface. Quote the receiver, transmitter, cable and mounting scope separately. Price and delivery are confirmed during quotation.
