SICK ES21 Series Emergency Stop Push Button, 3A Contact Current, 250V AC Contact AC Voltage - ES21-CG2001 / 6036140

This emergency stop push button serves as a safety command device for panel-mounted installations, providing a Compact non‑illuminated actuation point to interrupt hazardous machinery operation. It is designed for individual wiring with diagnostic-capable connections and operates across a wide ambient temperature range suitable for industrial environments.

Features and Benefits:

• 2NC safety contacts offering positive action for secure interruption
• Slow-action switching delivering controlled contact engagement
• 3A rated current enabling switching at 250V AC loads
• Supports 24V DC operation for low-voltage control circuits
• Screw-terminal connection allowing conductor cross-sections up to 2.5mm²

Applications

• Used with machine control panels requiring emergency shutdown
• Suitable for linking to safety circuits with diagnostic wiring
• Ideal for industrial systems needing Compact panel actuation
• Can be used in environments with broad temperature ranges
• Used for retrofitting control enclosures with safety contacts

What electrical life can I expect under rated load?

The switch provides an electrical life of 1 x 10^6 switching cycles at rated load.

How should the device be mounted on a control panel?

It is a panel-mount version designed for secure front-panel installation with screw-terminal wiring.

Which certifications cover hazardous-area use and conformity?

It holds UL hazardous-area certification and declarations of conformity for the EU and UK.

What are the connection limits for wiring conductors?

Terminals accept conductor cross-sections up to 2.5mm² via screw connections.
