Siemens 3SE5 Series Safety Switch, 20N Operating Force, 400V Switching Voltage - 3SE5112-0CA00

This safety switch is a mechanical interlock device designed for industrial access protection and position monitoring. Housed in a metal enclosure with M20 x1.5 conduit entry, it provides positive-opening snap-action contacts for safety-related applications. The unit operates across a wide ambient range and is suitable for environments requiring robust ingress protection and routine cyclic operation.

Features and Benefits:

• IP66/IP67-rated enclosure for harsh environmental protection
• Positive-opening contact mechanism for safety-compliant interruption
• 15 000 000 mechanical cycles for extended operational lifespan
• 20N minimum actuating force for predictable actuation behaviour
• Screw Terminal connection enabling secure electrical termination

Applications

• Suitable for machine-guard interlock monitoring in manufacturing
• Used with conveyor access doors requiring positive-opening switch
• Ideal for panels needing a Compact metal-housed safety device
• Can be used for guarding systems exposed to dust and water
• Suitable for installations requiring an M20 conduit entry point

What is the rated insulation voltage for the device?

The insulation rating is 400V, supporting typical industrial control voltages.

How does the unit perform under mechanical stress?

It withstands shock of 30g/11ms and vibration of 0.35mm/5g per IEC tests.

What cable entry and conductor types are supported?

A single M20 x1.5 conduit entry is provided and screw terminals accept solid 0.5…1.5mm² and 2x0.5…0.75mm² conductors.

What are the thermal and storage limits for use and transport?

Operational temperature range is -25°C…+85°C and storage range is -40°C…+90°C.
