Safety switch with magnetic locking MLP1 - SICK

The MLP1 is a transponder safety switch with magnetic locking which ensures reliable process protection for partially or fully automated production systems. It works with non-contact actuators and is used to monitor movable physical guards. Thanks to reliable door monitoring (Performance Level e), the MLP1 ensures a high level of safety of machine systems without overrun movement, preventing unauthorized access and therefore unplanned process interruption.

The safety switch featuring a magnetic locking function is the efficient solution for applications that require process protection in addition to the safety function. The transponder safety switch uses self-monitored semiconductor outputs to guarantee maximum safety for door monitoring. What’s more, a strong electromagnet ensures that the maintenance door stays closed and the production process is not interrupted. The combination of these two low-wear technologies provides high door offset tolerance and increases the availability of the machine. The innovative mounting concept and flat actuator enable optimum integration into the machine design.

Features

500 N magnetic locking force, 25 N retaining force;
PL e / Cat. 4 (EN ISO 13849), SIL3 (EN 61508) for door monitoring;
Offset tolerance of ± 5 mm;
Enclosure rating IP67;
Standard or integrated mounting;
Variants with two M12 plug connectors for simple cascading.

Advantages

Magnetic locking function prevents the protective door from being opened and therefore avoids unwanted interruption to the production process;
Maximum safety for door monitoring with two self-monitored semiconductor outputs (oSSds);
High level of machine availability due to large door offset tolerance;
Long product service life due to lowwear and low-maintenance configuration;
Discreet integration into the machine design thanks to innovative mounting option;
Quick connection and simple cascading via M12 plug connector reduce costs and the amount of wiring required;
Flat actuator without protruding parts minimizes risk of injury.
