SICK MLP1 Series Safety Switch, 60mm Length, Aluminium Housing - MLP1-SMUA0AC

This safety switch is an IP67-rated interlock designed for industrial access protection where electrical locking is required. It uses RFID sensing and a power-to-lock mechanism to secure guards and doors while providing self-monitoring semiconductor outputs for safety functions. The unit operates within standard industrial ambient conditions and includes an actuator for straightforward installation.

Features and Benefits:

• SIL3 safety integrity for high-risk functional applications
• Category4 safety architecture delivering PL e performance
• Power-to-lock operation with 350mA lock current when Active
• Self-monitoring OSSD outputs with ≤100mA output current
• IP67 aluminium housing allowing outdoor and washdown use

Applications

• Suitable for safeguarding production cell access points
• Ideal for use on electrically locked safety guards
• Used with control systems requiring OSSD diagnostics
• Can be used for machine doors needing coded interlocks
• Suitable for environments with frequent cleaning operations

What supply voltages are required for operation?

The sensor and magnet both use 24V DC with specified operating ranges for individual and cascade connections.

How does cascade connection affect timing?

Response, release and risk times increase proportionately in a cascade by the number of connected switches.

Which outputs indicate diagnostics and safety status?

Two self-monitoring semiconductor outputs provide safety signals and a separate diagnostic output offers status information.

What materials are used for the actuator and Anchor plate?

The actuator housing is fibreglass-reinforced PVC and the Anchor plate is nickel-plated steel.
