IEC touch-sensitive sensor: normally closed 3 wire with connector
Touch-sensitive sensor form: Normally Closed 3 Wire with Connector.
In plain English
What does IEC touch-sensitive sensor: normally closed 3 wire with connector mean?
A touch-sensitive sensor changes its output when its sensing surface is touched under the specified operating conditions. This entry identifies the normally closed 3 wire with connector form in the publisher's IEC-context family.
A simple example
An operator station may use the sensor as a controller input while keeping the powered sensor circuit separate from the load it commands. The normally-closed designation starts with a conducting output or closed contact in the documented reference condition; operation changes that state. The three-wire form distinguishes supply, return and switching output. Confirm sourcing or sinking operation from the actual sensor circuit before connecting it to an input.
What the drawings help you do
The connector variant adds a separable field interface. Keep the mating connector designation, pin numbers and cable-core mapping visible at that boundary. The mark does not establish a safety-rated enabling switch or guaranteed operation with every glove. Sensitivity, environmental suitability and output type need selected-device data.

Information to show or reference
- Identify the target, sensing mode and expected normal condition.
- Label supply, output and connector pins from the actual device diagram.
- Reference output circuit type, operating range and controller input.
A distinction that matters
This entry adds the normally closed 3 wire with connector detail to the broader touch-sensitive sensor family. The mark does not establish a safety-rated enabling switch or guaranteed operation with every glove. Sensitivity, environmental suitability and output type need selected-device data.
