Dual NO + NC Output Versatility: Provides complementary Normally Open and Normally Closed logic in a single unit, allowing universal compatibility with various printer controller mainboards.
Carriage Home & Limit Protection: Acts as a reliable home position origin sensor and X/Y-axis travel limit switch to prevent printhead collisions with physical carriage bumpers.
Non-Contact Precision Detection: Utilizes inductive or optical sensing technology to detect metallic targets or media position without physical friction or mechanical wear.

| Contact State | NO + NC (Normally Open and Normally Closed complementary outputs) |
The NPN NO-NC Switch (Proximity / Photoelectric Sensor Switch) is an essential limit and positioning spare part designed for digital printing machines, UV flatbed printers, eco-solvent plotters, and textile machinery. Featuring a dual output (Normally Open + Normally Closed) NPN transistor configuration, it provides precise non-contact detection of printer carriage home positions, media edge alignment, and gantry travel limits.
