Ultrasonic Sensors - 7106 T18U Specifications (cont’d) T18U Specifications

Output Response TimeNORMAL resolution mode: 2 milliseconds ON and OFF HIGH resolution mode: 1 millisecond ON and OFF Rep RateNORMAL resolution mode: 125 Hz max. HIGH resolution mode: 200 Hz max. Mechanical Sensing Repeatability at 300 mm rangeNORMAL resolution mode: less than 2 mm HIGH resolution mode: less than 1 mm Beam Angle (-3dB full angle) 15 ± 2Ëš Indicators Emitters have a green LED for dc power ON. Receivers have two LED’s, one yellow and one green. Indications are as follows: Green ON steady: dc power ON Green flashing: output overloaded Yellow flashing: sonic signal received (flash rate is proportional to received signal strength; flash is from full to half intensity). Construction T-style yellow PBT polyester housing with black PBT polyester back cover. Transducer housing is threaded M18 x 1. Mating jam nut is supplied for mounting. Acoustic face is epoxy reinforced. Circuitry is epoxy-encapsulated. Rated NEMA 6P, IEC IP67. ConnectionsEmitters: 2 m long attached PVC- covered 2-wire cable or 4-pin Euro-style quick-disconnect fitting.
