Different devices of the Gate signal transmission system

Signal transmission

  • Wear-free signal transmission
  • Several safety edges can be monitored safely and reliably with just one device

Electrical signal transmission – radio, inductive and wired

During signal evaluation on automatic gates, information regarding the status of safety edges is transmitted to the switching device securely and contact-free, via either radio or induction. This switching device monitors the safety edges that emit signals for actuation and interrupts.

InTra6 inductive signal transmission

This technology is used on automatic sliding gates. The status of the pressure-sensitive safety edges on the moving part of the gate is induced reliably and contact-free in a steel cable by means of a converter and transmitted to the switching device via a fixed coil.

The stationary safety edges can be connected directly to the switching device. This simultaneously solves the problem of wear that is encountered with conventional cable solutions.

With InTra6, up to four safety edge circuits can be reliably monitored with just one system.

The following products are based on inductive signal transmission:


Radio signal transmission

The radio signal transmission system is primarily used in the field of automatic gates.

The status of safety edges, which are fixed to the mobile part of the gate, is transmitted contact-free via a secure, bidirectional radio link to the switching device, where the opening or closing pulse is triggered immediately.

Depending on your application and needs, you can select either the one-channel or one of the two-channel variants.

The following products are based on radio technology:

       RFGate 3

       RFGate 2

       ExpertSystem XRF

Wired evaluation

Switching devices monitor the contact mats and safety edges for actuation and interrupts. These connected sensors with a terminating resistor of 8.2 kOhm are monitored for a change in the quiescent current. If the sensor is actuated, the total resistance drops, which causes a defined switching threshold to be undershot. The status LED lights up and the switching operation is triggered immediately.

The following products are based on wired signal transmission:
