Mini Halleffect Proximity Sensor — compact, reliable magnetic switch for noncontact detection Why choose this sensor Noncontact Halleffect sensing eliminates mechanical wear and provides consistent switching over time. Detects magnets at distances up to 25 mm, giving flexible mounting options and reliable activation without physical contact. Compact square 'mini' form factor fits tight spaces and simple installations where size matters. Available in NPN or PNP normallyopen (NO) output configurations to match common control and PLC input wiring; this listing corresponds to the Hall PNP NO variant. Key features and attributes Sensing principle: Halleffect magnetic induction for stable, repeatable magnetic detection. Output types: NPN or PNP, Normally Open (NO) — standard logiccompatible switching behavior for industrial controllers and circuits. Detection distance: 25 mm (maximum switching distance to an appropriate magnet). Form factor: Mini square switch design for compact installations and ease of mounting in limited spaces. Functionality: Noncontact magnetic proximity sensing for position detection, limit switching, presence detection, and simple on/off control signals. Benefits — how it solves problems Replaces mechanical switches in applications where contact wear, dust, oil, or vibration cause failures; Hall sensing offers longer life and lower maintenance. Makes installation and alignment easier because the sensor detects the magnetic field across a gap up to 25 mm, reducing the need for precise physical contact. Simplifies wiring choices with industrystandard NPN/PNP outputs and normally open switching behavior, improving compatibility with PLCs, controllers, and relay inputs. Typical applications Industrial automation: Endoftravel/limit detection on linear actuators, slides, or small conveyor sections where noncontact sensing reduces downtime. Robotics and motion control: Compact position sensing for arms, grippers, or tool changers where space is limited and reliable repeatable switching is required. Access and security: Magnetic door or hatch monitoring where the sensor can be placed out of the direct mechanical path and detect a magnet reliably at up to 25 mm. What to expect A compact, solidstate magnetic switch that provides reliable, repeatable NO switching when used with a suitable magnet and compatible NPN/PNP input. Choice of NPN or PNP logic to match your control system; the listed variant is Hall PNP NO. Note: Use with an appropriate magnet and ensure wiring matches the selected output type (NPN or PNP) and your control input requirements.
