Key Features & Specifications:

Feature Specification
Sensor Type Inductive Proximity Sensor (Short-Cylinder)
Operating Principle Generates an electromagnetic field to detect the presence of metal targets without physical contact.
Housing Material Stainless Steel (V4A / AISI 316L) - Highly resistant to corrosion, chemicals, and cleaning agents.
Thread Size M12 x 1
Sensing Distance 2 mm (Fixed, non-adjustable). Note: The "3N1361" typ number indicates a 2mm range.
Output Type PNP Normally Open (NO) (Also known as "sourcing" output). The output switch provides +V (24V) when a target is detected.
Output Function NO (Normally Open) - The output is off in the idle state and switches on when a target is present.
Wiring 3-wire DC: Brown (+V / 24V DC), Blue (0V / GND), Black (Output Signal)
Supply Voltage 10...30 V DC
Current Consumption Max. 200 mA
Switching Frequency 2 kHz (2,000 switching operations per second)
LED Indicator Integrated LED for visual status indication (power and switching state).
Protection Rating IP67 - Dust-tight and protected against temporary immersion in water (up to 1m for 30 minutes).
Connection Type Cable (2 m length, PUR jacket). The specific variant (e.g., straight or angled connector) should be confirmed from the exact order code.
Standard Complies with EN 60947-5-2.
3. Ordering Information (Typ Number Decoding):

WTB4S: Product Series (Inductive Sensor)

3: M12 Housing Thread

N: Non-Flush Mountable (The sensor can detect metals both from the front and laterally. Requires more side clearance during installation).

1361: Specific variant code denoting 2mm range, PNP NO output, and cable connection.

4. Typical Applications:
This sensor is ideal for use in:

Machine building and packaging machinery

Detecting the position of metal parts (e.g., pistons, clamps, tools)

Counting metal objects on conveyors

End position sensing on actuators

Automated assembly systems

Applications requiring frequent wash-downs or exposure to coolants and oils (due to its stainless-steel housing and IP67 rating).
