Emergency Stop Device with OSSD and Shroud (ESLP-SS-Z)

The ESL(P)-SS-Z is a robust stainless steel emergency stop with a protective button shroud, OSSD outputs, LED diagnostics and an IP69K rating, making it ideal for demanding industrial environments where resistance to water, dust and impact is required.

Designed for exposed conveyors and machinery where guarding is not practical, the ESL(P)-SS-Z allows operators to safely shut down a machine, system or process in an emergency. When used with a suitable safety monitoring controller, it can achieve CAT4/PLe, even when connected in series with up to 30 Z-Range devices.

The pulsed OSSD outputs and internal self-monitoring allow faults to be detected immediately, with clear indication via the raised LED or auxiliary output. A special safety trip lid mechanism ensures the safety contacts open if the lid is removed, adding an extra level of protection.

Manufactured from 316 stainless steel, the ESL(P)-SS-Z provides IP69K protection for high-pressure washdown, chemical cleaning and CIP/SIP applications.

Important Notes
Where the risk assessment identifies that inadvertent operation of the E-Stop button may occur during use or breakage and loss of the button function is foreseen, it may be preferable to specify the protection shroud version. When required by local regulations, please affix the supplied yellow emergency stop sticker.
