Ribbon Electrode Bands and Point Sensors available.
Model Number Legend
*1. The applicable models of the K7L depend on the model of the Socket. If the correct Socket is not used, the K7L nameplate will be upside down.
*2. The UL listing applies only when the Sensor is used in combination with a Push-In Socket (P2RF-08-PU). By itself, the K7L is UL recognized.
