The SR50-LC was retired in March 2007; some replacement parts remain available (see Ordering Info). This version of the SR50 Ultrasonic Distance Sensor had a connector rather than the standard pigtails. The connector attached to the MetData1 Weather Station.
The "-LC" version of this product terminates in a connector (instead of pigtails) for use with a CS110 Electric Field Meter or MetData1 Weather Station. The length of the cable is specified at the time of order.
