Limit Switches PL-05N NPN (Normally Open)
Electronic position sensing limit switches are utilized for detecting metal objects or workpieces in automated systems such as CNC machinery, packaging machines, printing equipment, and various industrial applications.
These switches feature an NPN Normally Open (N.O.) output. When an object is detected, the output terminal changes state to signal the control system, such as a PLC or microcontroller, to initiate the desired operation.
The sensor is compact and easy to install, providing stable and accurate performance. It is suitable for automated control applications requiring durability and rapid response.
Product Features
- Operating Voltage: 10–30V DC
- Output Type: NPN (Open Collector)
- Operation Mode: Normally Open (N.O.)
- Wiring:
- Brown → +V
- Blue → 0V (GND)
- Black → Output Signal
- Functionality: When the sensor detects an object, the output (Black wire) transitions from open to closed (pulled down to ground).
- Suitable for detecting metallic or ferrous objects.
- Fast response and precise operation.
- Durable construction suitable for general industrial applications.
Typical Applications
- As a limit switch in machinery.
- Detecting the position of shafts or workpieces in automated systems.
- Used in PLC, CNC, or robotic control systems.
- Metal detection on production lines.
Usage Recommendations
- Verify that the operating voltage matches the specified range (10–30VDC).
- Connect wiring according to color coding to prevent damage.
- Use with loads not exceeding the specified current rating (recommended not to exceed 200–300mA).
- If operating in dusty or wet environments, confirm the IP Rating before installation.
