ABB Jokab Turn Release Illuminated Emergency Stop Push Button, Surface Mount, 32.2 mm Cutout, 2 2TLA030051R0200 Smile 12 EA

The ABB Jokab 2TLA030051R0200 Smile 12 EA Turn Release Illuminated Emergency Stop Push Button is engineered to meet demanding industrial safety requirements. This unit is equipped with a high-visibility red actuator that illuminates when engaged, providing immediate visual feedback in low-light or emergency situations. The turn-release action is deliberately designed to avoid accidental reset, requiring a conscious operator action to restore circuit continuity and prevent inadvertent equipment restarts during critical maintenance.

The device features a robust plastic enclosure, which safeguards internal components against dust and splashes in compliance with IP65 standards. This ensures long-term performance in manufacturing, automation, and assembly environments. The push button is intended for surface mounting and requires a standard 32.2 mm panel cutout, making it compatible with a wide range of electrical control panels and machine cabinets.

Electrical safety is facilitated by the provision of dual normally closed (2 NC) contacts, rated for operation in 24V DC systems - common in modern industrial control circuits. The illuminated actuator is not only a safety aid but also supports operator awareness of machine status. Connections are streamlined through an M12 connector, speeding up installation and maintenance, and enabling rapid disconnection for equipment changes or servicing.

Typical use cases for this ABB Jokab Smile 12 EA series push button include use in automated assembly lines for conveyor emergency stops, control cabinets in process control environments, machine-tool safety isolation in manufacturing plants, and shutdown operations in processing stations requiring reliable human interface devices. Its compact cutout and surface mount design allow for flexible deployment in new builds or retrofits.

The plastic housing provides a combination of electrical insulation and corrosion resistance, ensuring that the emergency stop remains functional even in aggressive industrial atmospheres. The sealed actuator and enclosure further defend sensitive contacts from dust and water ingress, reducing the likelihood of electrical failure or accidental operation.

Operators benefit from the clear tactile feedback of the turn-release mechanism and the unmistakable red illumination during emergencies, ensuring fast, properly documented responses to hazardous events. This model is a proven solution where industrial safety, reliability, and fast visual indication are required for machine and personnel protection.
