Description
Limit Switches PL-05P PNP
Limit Switches PL-05P (PNP, Normally Open)
An electronic proximity switch designed for position detection and metal sensing. This compact sensor is utilized in automated control systems such as CNC machinery, packaging equipment, printing presses, industrial robotics, and various production lines.
This model features a PNP Normally Open (N.O.) output. When a metallic object enters the sensing range, the sensor outputs a positive voltage (+V) signal to control external devices like PLCs or microcontrollers.
The sensor housing is green, compact, and designed for easy installation and convenient operation, offering high precision and stable performance.
Product Specifications
- Operating Voltage: 10–30V DC
- Output Type: PNP (Source Output)
- Operating Mode: Normally Open (N.O.)
- Wiring Configuration:
Brown → +V
Blue → 0V (GND)
Black → Output (+V signal when triggered)
- Functionality: When the sensor detects an object, the Output pin supplies a positive voltage (+V).
- Detection: Accurately detects ferrous metals.
- Compact Size: Facilitates installation in confined spaces.
- Performance: Offers rapid response time and high resistance to noise interference.
General Applications
- Used as a Limit Switch for detecting the position or endpoint of workpieces.
- Applicable in automated machinery, packaging machines, printing presses, and robotic arms.
- Metal detection in production control systems.
- Compatible with PLCs or systems supporting PNP (sourcing) inputs.
Usage Recommendations
- Verify operating voltage (10–30VDC) before connection.
- Connect wiring according to the diagram (Brown = +V, Blue = 0V, Black = Output).
- Connect only to loads or inputs compatible with PNP signals.
- For dusty or humid environments, verify the IP rating before installation.
