Functions

Conveyor belt misalignment control – the switch detects belt deviation from the normal operating trajectory and activates a signal or stops the system
Dual contact output (2×SPDT) – allows simultaneous transmission of a warning signal and an emergency stop command
High protection class IP67 – ensures reliable operation in dusty, humid or outdoor environments
Wide temperature range – stable operation from –40°C to +50°C, suitable for demanding industrial conditions
Reliable mechanical construction – 75–100 N operating force allows accurate detection of belt contact and deviation
Fast response to deviation – first level activation angle – 15°, enabling early detection of the problem

Application

For industrial engineers and project designers: Used in the design of automated conveying systems where safe conveyor operation must be ensured. Integrated into PLC, SCADA or industrial controller systems as a protection element. Suitable for projects in mining industry, cement plants, logistics terminals, grain elevators, warehouse automation and power generation facilities.

For electricians and automation specialists: The switch is easily integrated into existing conveyor safety systems. Used for protection against belt slipping, alarm systems, automatic stopping functions and PLC control systems.

For maintenance specialists: The device helps prevent conveyor belt damage, reduce downtime, detect mechanical defects in conveyor systems and improve operational safety in industrial environments.

Advantages

High protection class IP67 – resistant to dust and water
2×SPDT contacts – flexible integration into control systems
Wide operating temperature range –40°C to +50°C
CE and ISO certificates
Suitable for demanding industrial environments
Early detection of conveyor belt deviation
Improves equipment safety and reduces downtime

Disadvantages

Requires proper mechanical installation on the conveyor structure
Used only for belt misalignment detection – not for full diagnostics of all conveyor types
For full protection, several switches are often installed along the entire conveyor length
