Norelem introduces emergency stop buttons and position switches

German standard component manufacturer Norelem is introducing a new range of emergency stop buttons and position switches to help improve operational safety.

As stated by the Machinery Directive, machines and systems must be equipped with a device to shut them down quickly in emergency situations. Norelem now offer a variety of products that satisfy this need, which will ensure safe shutdowns in different plant environments. The products in the two ranges of emergency stop buttons and position switches are designed to manually switch off machines and systems in the event of danger.

“In manufacturing, safety is absolutely paramount. Having the correct systems in place in the case of emergency situations is a necessity in all industries” says Marcus Schneck, CEO of Norelem. “Of course, it would be ideal that these products would never have to be used, but we cannot pretend that things go 100% as planned all of the time. That is why we are introducing our new range of mechanical position switches and emergency stop buttons.”

The emergency stop buttons from Norelem are used to manually switch off machines and systems in the event of an emergency. They are designed to be tamper-proof and easily recognisable through a standard-compliant mushroom button with a yellow or red background colour. To prevent any accidental actuation, the button must overcome a certain pressure point in order to be activated. The emergency stop button is unlocked by turning it to the right or left and all buttons are available with anti-lock collars.

The components comply with DIN EN ISO 13850 and offer a long service life of at least 50,000 switching cycles. Depending on the version, they offer a tightness of up to IP67 and are equipped with two openers for increased safety.

The emergency stop buttons are available for installation openings with diameters of 16.2mm and 22.3mm and in the housing as a surface-mounted version. The Minibox housing connection is especially suitable for aluminium profiles, as it is narrow, ready-to-connect, fully equipped housing, which includes an emergency stop button.

The mechanical position switches are complete position switches with a compact design. Their plastic housing is equipped with a hinged and captive housing cover. An M20x1.5 aperture is provided to pass the connecting cables through, which can be connected with screw terminals. The switches are equipped with a thrust pin actuator; however, this can be replaced by another actuator if required for a different situation.
