Emergency stops are used for machines and robots in industry and in the marine environment. Emergency stops are of course also essential for doors, escalators, transport vehicles, lifts and cranes. The criteria set for emergency stops are that they must always be ready for use and that their activation must result in the immediate shutdown of the machine. Resetting the emergency stop must not initiate a re-start and the colour is always red/yellow. Emergency stops are available in many designs and they often have a high IP classification of a minimum of IP65 for “clean” environments and IP69K for the very highest safety level. Combine them with wiring, a control box assembly or build them into a system.
A compact emergency stop equipped with an additional normally open (NO) contact is available for applications where extra signalling or controlled shutdown is required. While emergency stops are typically supplied with normally closed contacts, this variant includes an extra signal contact that remains open under normal conditions. The added functionality enables, for example, a controlled shutdown to be triggered from another location via the control panel, depending on the installation and safety requirements. The device can be supplied either with quick‑connect terminals or as a through‑hole (THT) version for direct PCB mounting. It may also be integrated into a complete modular system, which can be configured to meet specific application needs.
The emergency stop is suitable for mounting holes with a diameter of 22.3 mm. The depth behind the panel is 9.2 for PCB mounting and 27 mm for quick connect terminals.
Control boxes can be permanently mounted, work as handheld units or be mounted on a DIN rail. The handheld units can be equipped with a magnet system for attachment to a vehicle, for example. The permanently mounted control boxes can work as a control box for doors or as a control unit for hydraulic systems for vehicles. The control boxes are often fully customised, where different types of selector switches, buttons and displays are included and it is of course the application that determines which enclosure class is required and which emergency stop works best in the box.
