Emergency Stop Buttons
An emergency stop button is a red mushroom-head button that, when pressed in a hazardous situation, breaks the machine's emergency stop circuit and stays locked in the pressed position until it is manually reset. It is used on machine housings, panel doors and along conveyors to stop hazardous motion by the shortest route. The category includes models with a 22 mm mounting diameter and 40 mm head, reset by twisting or by key, illuminated and non-illuminated, as well as enclosed types, from brands such as Schneider Electric, EMAS and ABB. Select the emergency stop button by mounting diameter, head diameter, reset method, number of NC contacts and IP rating, based on the number of channels the machine's safety circuit requires. The stop circuit is wired through the NC contact; the NO contact on 1NO + 1NC models is mostly for status indication. The principles of the emergency stop function are defined in EN ISO 13850, and emergency stop devices with mechanical latching in IEC 60947-5-5. A spring-return red mushroom-head button that returns when released is not a substitute for an emergency stop button because it does not lock in the pressed position.

How to choose Emergency Stop Buttons
An emergency stop button is a red mushroom-head button that, when pressed in a hazardous situation, breaks the machine's emergency stop circuit and stays locked in the pressed position until it is manually reset. It is used on machine housings, panel doors and along conveyors to stop hazardous motion by the shortest route.
- Separate sensing, motion control, logic processing and operator interface requirements.
- Select signal type, supply voltage, communication protocol and I/O count for the machine network.
- Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
