IJ Instruments is a reliable source for Corseener proximity switches and sensors — inductive, capacitive and photoelectric detection devices used across machine automation, conveyor systems and control panel design. Share your target material, sensing distance and output requirement, and we'll help you select the right sensor type and model.
Product Range
Each proximity switch technology detects targets differently — the right choice depends mainly on what you're detecting and from how far away.
Detects metal targets only, using an electromagnetic field — no contact needed. Available in threaded cylindrical (Ø6.5 to M30), ring and square styles, DC 3-wire and 4-wire, standard and wide-temperature (-40°C) variants.
View Full Details →Detects metallic and non-metallic targets — liquids, powders, plastics, wood, glass — by sensing changes in capacitance. Sensitivity is adjustable via potentiometer to tune for material and mounting condition.
View Full Details →Uses an infrared or red light beam to detect objects at longer range than inductive or capacitive types — up to 5 metres. Available in diffuse-reflective (with background suppression) and retro-reflective (mirror) configurations.
View Full Details →Including relay-type optical grating (multi-beam area/object detection). Contact us to check availability.
Quick Comparison
