Product catalog summary

Introduction: The document is a comprehensive guide on systematic control switchgear, focusing on emergency pull-wire, belt-alignment, and slack-wire switches. It includes specifications, design principles, and application guidelines for various switch series.

Company Overview: Steute Schaltgeräte GmbH & Co. KG is a medium-sized company in East Westphalia, specializing in innovative switchgear solutions across four business fields: Wireless, Automation, Extreme, and Meditec. Their products meet international standards.

Emergency Pull-Wire Switches: These switches are essential for industrial applications, particularly in transport and conveyor systems. They comply with EN 60947-5-5 and the Machinery Directive 2006/42/EC, featuring wire-break detection and one-side or two-side actuation options.

Design and Operation: The switches operate by pre-tensioning the pull-wire, affecting NC and NO contacts. Specific mounting conditions and accessories are required, with compensation springs used to manage thermal changes and actuating travel.

Technical Information: The document details the function principle, compensation spring application, and mounting instructions, emphasizing the use of steute's pull-wires for reliability and safety.

Selection Table: A table lists various series of emergency pull-wire switches, specifying enclosure material, actuation type, number of contacts, and maximum pull-wire length.

Specifications: Detailed specifications for series like ZS 70, ZS 71, and ZS 73 include enclosure materials, wire length capacities, and compliance with standards like IEC/EN 60947-5-1 and EN ISO 13849-1.

Technical Data: All series feature silver contact material, snap action switching systems, and are rated for over 100,000 operations. They support ambient temperatures from -25°C to +70°C.

Mounting and Installation: Instructions include options for installation with or without tension springs and the need for intermediate wire supports.

Standards and Approvals: The switches comply with IEC/EN 60947-5-1, IEC/EN 60947-5-5, EN 418, and EN ISO 13849-1 standards.

Features and Options: Options include push-button or key release mechanisms, indicator lamps, and watertight collars. Maximum wire lengths vary by model, up to 130 meters.

Applications: Suitable for environments requiring reliable emergency stop mechanisms, with options for harsh conditions and long wire lengths.

Recommendations: The document recommends using specific components like cable tensioner systems and advises on the placement of belt-alignment switches.

Data Summary: Graphs and tables illustrate temperature and length parameters for installation, along with ordering details for various switch models.
