Compare Speed Sensors

	LS100-M12A Optical Laser Sensor	IN100 Inductive Proximity Sensor
Principle	Reflected invisible red laser beam	Eddy currents in metal target
Speed Range	1-250,000 RPM	1-24,000 RPM
Sensing Distance	1 in. to 25 ft. (25,4 mm to 7,62 m)	0.15 in (4 mm) maximum sensing distance
Low RPM Accuracy	Good with fine targets	Moderate (single target)
Target Material	Works on any target material when used with reflective tape, including: Wood Paper Plastic Rubber Metal	Target must be metal; non-ferrous metals reduce range: Iron - 100% rated distance Stainless Steel - 50% rated distance Brass, Aluminum, Copper - 40% rated distance
Minimum Target Size	n/a	0.45 in. (12 mm) diameter
On-Target Indicator	Green LED indicator confirms alignment without a separate meter	Red LED indicator provides quick visual confirmation of setup without additional tools
Input Power Required	10-24 Vdc	3-36 Vdc
Housing Material	316L stainless steel and ABS nosepiece	Brass housing
Output	Open connector / TTL compatible	PNP open connector
Environment	IP67-rated housing; clear optical path required	IP67-rated resistance to dust and oil
Best For	Non-Metal Targets Long Distances High RPM range	Metal Shafts Conveyors Machine Tools
