SICK ES21 Series Emergency Stop Push Button, 3A Contact Current, IP65 - ES21-SA10F1 / 6036148

This emergency stop push button provides a manual safety cut-off for industrial machinery, delivering slow-action switching with a rotary turn-to-release mechanism. It is maintenance‑suitable for surface‑mounted panels and offers protection against ingress for use in exposed operational environments. The device uses screw‑terminal connections and supports individual wiring with diagnostic capability where required.

Features and Benefits:

• 3A rated contact current delivers reliable load interruption
• 250V AC and 24V DC operation supports mixed‑voltage systems
• 1NO/2NC contact layout enables fail‑safe circuit implementation
• Rotary release actuation permits quick manual reset after stop
• IP65 housing resists dust and water for robust installation

Applications

• Suitable for machine emergency shutdown circuits in factories
• Used with control panels requiring surface‑mount stops
• Ideal for production lines with mixed AC and low‑voltage DC
• Can be used for safety stations requiring screw connections
• Suitable for environments needing non‑illuminated safety switches

What connection method does it use for field wiring?

It employs screw connections via two M20 cable gland entry points for conductors up to 2.5mm².

What are the electrical switching capabilities at low voltage?

The device supports 24V DC switching at 2A and functions down to switching voltages ≥5V DC with switching currents ≥1mA.

What mechanical endurance rating does it have?

The B10d parameter specifies a fatigue life of 2.5 x 10^5 switching cycles for reliability assessment.

What ambient conditions can it tolerate during operation?

It operates between -25°C and +60°C and can be stored between -25°C and +85°C.
