tion/current output
no moving parts; 200 mA sinking output TTL compatible; stainless steel NPN or PNP output; stainless steel; crystal sensing tip
Incorporates the principle of total optical reflection to create a fast, accurate, reliable, and
cost-effective solid state sensor with no moving parts. Used for the detection of liquid
level or liquid leaks, and are designed to switch digital I/O, LEDs, coil relays, buzzers,
and incandescent lamp indicators. Broad portfolio covers numerous potential applications
including home appliances, food and beverage, vending machines, medical, industrial
compressors, HVAC, transportation, aerospace, and military.
