Steute ex zs 80 1o/ 1s wvd emergency pull-wire switch with safety function

What is the Steute EX ZS 80 1O/1S WVD Emergency Pull-Wire Switch?

The Steute EX ZS 80 1O/1S WVD is an industrial emergency pull-wire switch designed for hazardous and explosive environments (EX zones). It allows operators to trigger an emergency stop by pulling a wire installed along industrial conveyors, processing lines, and machinery areas.

Unlike standard emergency stop buttons, a pull-wire switch covers long distances—often several meters—making it accessible from anywhere along the installation path. This ensures immediate shutdown of equipment in case of danger, preventing accidents, equipment damage, or production downtime.

The model features 1 normally open (1O) and 1 normally closed (1S) contact configuration, offering reliable switching performance for safety circuits.

Key Features of the Steute EX ZS 80 1O/1S WVD

1. Explosion-Proof Construction

Designed for Zone 1 and Zone 21 hazardous areas, this switch ensures safe operation in environments with gas, dust, or combustible materials. Its rugged housing protects internal components from sparks, heat, and impacts.

2. Long Monitoring Distance

The pull-wire system enables emergency stopping across conveyor belts or extended machinery sections, offering superior accessibility compared to localized emergency buttons.

3. High Mechanical Durability

Built to withstand tough industrial conditions, the switch features corrosion-resistant materials suitable for heavy industries like mining, marine environments, oil & gas facilities, and manufacturing units.

4. Reliable Contact System (1O/1S)

Equipped with:

• 1 Normally Open (NO) contact

• 1 Normally Closed (NC) contact

This ensures dependable signaling for emergency stop and safety monitoring circuits.

5. Easy Installation and Maintenance

The switch includes adjustable tension indicators, accessible terminals, and robust mounting options that simplify installation and reduce downtime during maintenance.

6. Visible Wire Tension Indicator

A clear display shows the correct wire tension, ensuring the system remains ready to operate. If tension drops, the switch trips automatically for safety assurance.

7. IP66 / IP67 Protection

Highly resistant to dust, water, moisture, and industrial contaminants—ideal for outdoor or harsh indoor environments.
