The CJF17E-05LA Proximity Switch is a non-contact sensor that detects a nearby object and sends a switching signal without any physical touch. With an NPN output and a normally open (NO) contact, it suits hobby automation, irrigation and pump control panels, small machines, and DIY electronics projects where you need reliable position or presence detection.
Key features
- Model CJF17E-05LA for easy reordering and matching.
- NPN output type for connecting to common control circuits and PLC inputs.
- Normally open (NO) contact that closes when a target is sensed.
- Non-contact operation means no moving parts to wear out, helping it stay reliable.
- Compact body that fits into tight panels and machine frames.
Typical uses
- Object and position detection on small machines and conveyors.
- Pump, valve, and irrigation control panels for level or position feedback.
- Automation, robotics, and DIY electronics builds.
- Counting and end-of-travel sensing for workshop tools.
How to choose / tips
- Confirm your circuit expects an NPN output and a NO contact before wiring.
- Match the supply voltage of your controller to the sensor's rating.
- Mount it firmly and keep the sensing face clear for steady triggering.
