Sensors for overload control on lifts with CAN output

Sensors for overload control on lifts with CAN output

To control overload on elevators or goods lifts, it is possible to use different kind of transducers: multirope sensors to install on the ropes or strain link to install on metal structure of lift cabin. Both of them allow to detect the weight of the cabin, avoiding possible overload. They can be connected to 699Plus digital device, in order to display measures and to set alarms for thresholds overcoming.

All of these sensors proposed by S2Tech are available with CANopen output. It guarantees reliability of the product, a safe and efficient use of it and high speed in trasmission of data.

Overload CANopen sensors are equipped with a built-in electronics, that allows them to be connected easily to 699Plus device with CAN communication protocol.

S2Tech sensors for elevators, available as CANopen version are:

  • 942DBCAN: it measures the load in the cabin by measuring the deformation (flexion) of the metal structure on which it is installed. Connection to CAN line of the elevator allow different diagnostics function and high safety during all the activities
  • MRL DBCAN: available for all sensor versions (100, 150 and 200). It has to be installed on all elevator ropes in order to guarantee an accurate and reliable measure. Built-in electronics simplifies its use in different applications and environments

Both 942 and MRL sensors have to be connected to 699Plus device to display measures detected by the sensor. 699 device is equipped with three relays that can be activated when set thresholds are overcome.

  • MRLC for belts: it is an updated version of MRL sensor and it is suitable for belts. In this case the 699Plus device is integrated directly on the sensor and it allows to read easier measurement values coming from the transducer installed on the ropes.


All of the presented products are available with digital RS485 or analog outputs too.
