Limit Touch Switch
NL
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.

Be sure to wire the cable correctly according to the color of each lead wire. Do not wire power lines or high-tension lines alongside the cable. The use of S3D2 is recommended as a power supply to the NL1. Contact your OMRON representative for the datasheet of the S3D2. +12 VDC Brown (Red) - Page 5 Note: 1. The force that pushes the actuator must not exceed 1.96 N. Note: Do not apply a force greater than 9.8 N to the plunger. 2. The antenna is replaceable. Contact your OMRON representative for details. Separated Antenna Models The dimensions provided for the NL1-SP, NL2-SP, NL1-SC, and NL2-SC are the external dimensions for the antennas.

Safety Precautions Refer to Safety Precautions for All Limit Switches. Antenna CAUTION <Shape and Extension> Make sure that the antenna does not come into contact If a metal plate is used as an antenna by connecting it to the built-in with the human body, otherwise an electric shock may or separated antenna of the NL, the surface area of the metal plate be received. - Page 7 NBR may deteriorate. Contact 4 cm min. your OMRON representative for details. • Make sure that the load is connected according to the connection diagram. The internal circuit of the NL will break due to mistakes in wiring or load short-circuiting.
