SICK ES21 Series Emergency Stop Push Button, 3A Contact Current, Illuminated - ES21-CH2111 / 6036143

This emergency stop push button provides a manually operated safety command for industrial panels, combining an illuminated actuator with a panel-mount contact module. It is designed for individual wiring with diagnostic-capable connections and operates across a wide ambient temperature range for use in varied machine environments.

Features and Benefits:

• 3A rated current delivers sufficient switching for control circuits
• 24V DC illumination reduces wiring complexity for indicator circuits
• 1NO2NC contact arrangement supports both signalling and safety circuits
• Slow action switching supports controlled interruption of loads at 250V AC
• Screw Terminal connection permits conductor sizes up to 2.5mm²

Applications

• Suitable for machine control panels requiring manual shutdown
• Ideal for safety reset and signalling on manufacturing lines
• Used with control relays and contactors in assembly stations
• Can be used for access gate emergency stopping in facilities

What supply voltage range does the illumination accept?

The illumination accepts 12V DC to 30V DC, nominally rated at 24V DC, and draws 8mA to 44mA depending on voltage.

How Durable are the switching and mechanical components?

The electrical life is 1x10⁶ switching cycles and mechanical life is 1x10⁶ cycles with a B10d Value of 250,000 cycles.

What environmental temperatures can it withstand during operation?

It operates between -30°C and +85°C and can be stored between -50°C and +85°C.

Which approvals and certifications accompany the device?

It carries UKCA, cULus, EN conformity declarations and China RoHS certification.
