Typical output signals
of sensors When using sensors, it is important to know the different types of electrical output
signals. Type A Sensors with switching signal output (binary signal output).
Examples – Proximity sensors
– Pressure sensors
– Filling level sensor
– Bimetal sensor As a rule, these sensors can be connected directly to programmable logical
controllers (PLC). Type B Sensors with pulse rate output.
Examples – Incremental length and rotary angle sensors. Generally, PLC-compatible interfaces are available. PLC requirements:
