SiTec Product Range
Pull Wire Emergency Stop Switches
Emergency stop anywhere along the conveyor. SiTec’s pull wire emergency stop switches allow operators to initiate an emergency stop command on a conveyor belt system from any point along its length, critical for preventing injury and equipment damage.
Key capabilities include:
- Positive break switches activated when the pull wire is initiated or if the wire breaks on tension systems
- Single- and double-sided switch configurations depending on conveyor length
- High-quality pull wire mechanisms designed for reliable long-term performance
- Options for aluminium, stainless steel, or durable Duroplast housings
- Fully compliant with EN ISO 13850 & DIN EN 60947-5-1.
These switches are ideal for conveyors used in raw materials processing, mining, ports, steelworks, and packaging lines.
Position Misalignment Switches (Belt Drift Switches)
Protect your conveyor belt from uneven wear, damage, and material loss. SiTec misalignment switches can be set at adjustable switching points to improve monitoring positions for belt tracking and respond automatically when misalignment occurs.
Features include:
- Roller-lever detection for precise triggering
- Adjustable switching points for pre-warning and shutdown
- Replaceable stainless-steel rollers
- Options for aluminium, stainless steel, or durable Duroplast housings.
SiTec misalignment switches help prevent costly belt damage, reduce spillage, and extend conveyor operating life.
Position Limit Switches
Reliable detection of mechanical end-positions on conveyor equipment. SiTec limit switches are engineered for accuracy and durability in extreme industrial environments. These switches:
- Detect contact from machine components via roller-lever actuation
- Trigger the next step in the process via an electrical signal
- Operate reliably in dusty, hot, cold, and corrosive environments
- Options for aluminium, stainless steel, or durable Duroplast housings.
Applications include machine sequencing, safety interlocking, and conveyor mechanical control.
Featured Products:
High-Temperature Position Misalignment Switch
Engineered for smelting plants, steel mills, and high-heat conveyors.

Frequently Asked Questions
SiTec switches are built for heavy industrial environments including mining, quarrying, steel production, cement plants, ports, and large-scale bulk-material handling. Their high durability makes them ideal for harsh indoor and outdoor conditions.
A pull-wire emergency stop switch allows operators to stop a conveyor at any point along its length by pulling a tensioned or non-tensioned rope. It is required wherever continuous emergency-stop access is needed, especially on long conveyors or where local push-button access is limited.
Misalignment, or belt drift, switches detect when a conveyor belt drifts off centre. As the belt edge contacts the roller lever, the switch triggers a warning or shutdown condition depending on the deflection angle. This prevents belt damage, material spillage, and costly downtime.
Single-sided switches are used on shorter conveyors with a pull rope installed on one side. Double-sided switches allow emergency stop activation from either side of the conveyor and are typically used on long conveyors or where safe access is required along both sides.
SiTec offers stainless steel, aluminium and Duroplast housings for corrosion-prone or high-moisture sites, and high-temperature misalignment switches rated from –50°C to +150°C for steel mills and smelting applications.
SiTec’s High-Temperature Position Misalignment Switch is engineered for steel, smelting, and hot-material conveying, with 5 million mechanical operations and IP67 protection, and are rated from –50°C to +150°C for steel mills and smelting applications.
Conveyer safety products devices from SiTec, Tekon & Leveltec can be grouped together as a system. For monitoring only, Wireless transmitters replace long cable runs by sending digital and analogue sensor data (plus temperature) via a mesh network up to 48 km. When connected to a Modbus gateway, each transmitter can activate a voltage-free contact for SCADA integration.
Limit switches detect the end of travel or mechanical position changes in conveyors, equipment, or machine components. They trigger the next control action in the system and are designed for heavy-duty operation in dusty, hot, or corrosive environments.
Leveltec stocks a broad range of SiTec safety and monitoring switches in Australia, with engineering support available for selection, integration, and conveyor safety upgrades.
We can configure housing materials, switching points, indicators, and special features (e.g., pressure equalisation, mount brackets, cable glands, roller types) to meet site-specific requirements.
