Siemens Rope Pull Switch Cable 10m

The Siemens 3SE7 Emergency Grab Wire Switch provides reliable safety monitoring for hazardous machine sections. Operators can activate the emergency stop by pulling the wire. Therefore, it improves safety across long conveyor systems and industrial setups.

Wide Coverage for Large Systems

This grab wire switch protects large systems, as its range depends on the wire length. As a result, it suits long conveyor belts and extensive machinery lines.

Moreover, systems that require pulling from both ends support monitoring of very long belt systems. Conveyor belt unbalance trackers also enhance safety in such applications.

Flexible Contact Configurations

The 3SE7 series offers multiple configurations:

• Up to 50m: 1NO + 1NC or 2NC
• Up to 75m: 1NO + 3NC
• Up to 2 × 75m: 2NO + 2NC

Therefore, users can choose the right configuration based on system requirements.

LED Indicator for Visibility

Some models include a factory-fitted red LED (24V DC). This light shows the switch status clearly. As a result, operators can see the condition from up to 50 meters away. Moreover, the onboard chip technology ensures reliable indication.

Safe and Reliable Operation

The switch uses positive opening NC contacts, which ensure safe disconnection. In addition, the system supports wire-break and wire-pull detection.

For one-sided operation, the system maintains tension using a turnbuckle. However, users must release the locking mechanism before resetting the switch. Therefore, it prevents accidental restart.

Durable Industrial Design

• Strong metal housing for durability
• Screw-mounted enclosure for secure installation
• IP65 rating for dust and water protection
• Operating temperature: -25°C to +70°C

Consequently, the switch performs reliably in harsh environments.
