ABB 1SFA Series Emergency Stop Push Button, 40mm Head Diameter, Red - 1SFA619552R1071 - CE4K1-10R-11


This emergency stop push button is a panel-mounted safety switch designed to provide Rapid manual shut-off in industrial control systems. It features a large mushroom-style head for straightforward actuation and a key-release mechanism to reset the device after an emergency stop. The unit is suited to demanding environments where certified hazardous-area performance and high ingress protection are required.

Features and Benefits:


• 1NO1NC contact arrangement for clear make-and-break function
• SPDT electrical switching rated 300V and 2A for control circuits
• Polyester housing provides chemical-resistant enclosure performance
• Screw terminals for secure, field-serviceable wiring connections
• Key release actuation prevents accidental restart after trip
• Two auxiliary contacts increase monitoring and safety circuit options

Applications


• Suitable for stopping automated conveyor lines in manufacturing
• Ideal for machine-tool emergency shutdown in workshops
• Used with control panels in hazardous-area production zones
• Can be used for safety interlocks on packaging machinery
• Suitable for retrofit safety upgrades in electrical cabinets

What ingress protection does it provide for wet or washdown areas?


The unit meets IP66, IP67 and IP69K ratings, offering dust-tight sealing and protection against high-pressure, high-temperature washdowns.

How does the key-release mechanism operate in practice?


After actuation the button remains latched and requires a removable key to release the head and permit restart, preventing unauthorised or accidental resets.

What approvals cover use in explosive atmospheres?


It holds both ATEX and IECEx certifications permitting installation in specified hazardous locations subject to local installation rules.

How many auxiliary contacts are available for safety monitoring?


There are two auxiliary contacts that can be used to feed redundant safety circuits or status-monitoring relays.
