Which Telco Technology Do I Need?

Start with your application requirement, then select the recommended technology to browse matching Telco products.

What do you need to detect?	Recommended technology	Why it fits
Objects over long distances or in demanding environments	Through-Beam Sensors	Separate transmitter and receiver provide maximum sensing range and highly reliable detection.
Objects when wiring is available from only one side	Retro-Reflective Sensors	The emitter and receiver share one housing while a reflector returns the beam from the opposite side.
General object presence without a receiver or reflector	Diffuse Proximity Sensors	The target reflects light back to the sensor for straightforward single-sided installation.
Objects positioned close to machinery or another background	Background Suppression Sensors	A defined sensing cutoff helps distinguish the intended target from surfaces behind it.
Small targets or restricted sensing locations	Fiber-Optic Sensors	Compact fiber sensing heads provide flexible detection where conventional sensor housings may not fit.
Remote sensing heads or centralized multi-channel control	Remote Photoelectric Systems	Remote sensors operate with separate Telco amplifiers for flexible installation and system control.
Objects across a doorway, conveyor, or wide opening	Light Curtains Industrial Light Curtains	Multiple beams monitor a larger detection field than a single-point photoelectric sensor.
Object height, profile, position, or dimensional measurement	Measuring Light Curtains	Multiple sensing beams and configurable outputs support measurement and process monitoring.
High-speed counting, edge detection, or fixed sensing geometry	Optical Fork Sensors Optical Frame Sensors	Fixed emitter-to-receiver alignment provides precise, repeatable detection of small or fast-moving objects.
Metal targets, nonmetallic materials, or liquid-level detection	Inductive Sensors Capacitive Sensors	Inductive sensors detect metal, while capacitive sensors can detect nonmetallic materials and liquids.
