Emergency pull wire switches are compact and robustEmergency pull wire switches are often used in machines and plants which are especially demanding. Adverse conditions can include dust and dirt, as well as damp, fluctuations in temperature and high levels of mechanical wear and tear. With the aim of providing customers with an 'Extreme' version for such applications, Steute has fundamentally redesigned its ZS 71 emergency pull wire switch.
One of the modifications is to replace metal with high-quality plastic as the enclosure material, making it suitable for long-term use in corrosive environments. Another change is a stainless steel draw gear. The mounting screws are also stainless steel.
Protected to IP67K, the ZS 71 'Extreme' can even be exposed to a high-pressure cleaner without any detrimental effect to its long-term functionality. Another variant in protection class IP67 is able to withstand cold temperatures of down to -40degC.
