NL2-SP 3M

Limit Touch Switch NL CSM NL DS E 2 2 Object Actuates Switch and Turns Built-in Monitor Indicator ON Instantaneous operation upon contact with extremely limited hysteresis for high-precision position detection. Detects minute displacement or lightweight objects with minimal operating force. Built-in LED indicator ensures easy operation monitoring. DC models provide versatile functions in combination with the S3D2 Sensor Controller. Be sure to read Safety Precautions on page 6 to 7 and Safety Precautions for All Limit Switches.

The NL3 has a capacitor and resistor for the protection of the built-in SCR. Therefore, the NL3 has leakage current. *2. The NL3 requires a current of 30 mA for circuit protection. Red (Brown) If the load current is less than 30 mA, connect the bleeder resistance R in i Power supply Load parallel with the load as shown below so that the total current of the load circuit will be 30 to 300 mA. White 100 VAC (Black) (200 VAC) Obtain R from the following formula. R NL3 Black (Blue) V R= (k) 30 i Make sure that the permissible power of the resistor is sufficient. *3.
