STM Sensors Inc., San Diego, CA, offers the MICROmote DL20JJ and DLV60JJ water detection sensors. The throughbeam photoelectric sensors use a 1450 nm IR light source to match the absorption spectrum of water and can provide level or bubble detection for medical technology or laboratory applications. The DL20JJ has a 0.4 mm spot dia. for use on ultra-thin capillaries, a 250 mm measuring distance, and its small body size (0.2 by 8 mm for the emitter and 0.2 mm by 12 mm for receiver) and high flex cables allow installation under extreme space restrictions. The DLV60JJ cubic sensor has a 500 mm sensing distance and is 6 by 6 by 12 mm. Sensors work with the company's MICROmote amplifiers.
