Model Number Legend
Note: If you want a Push-In Plus Terminal Socket, use the K7L-U@B. (The terminal
arrangement of a Push-In Plus Terminal Socket is upside down in comparison
with a Screw Terminal Socket.)
Ordering Information
*1. Accessories are available. Check the ratings for details.
*2. 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.

resistance
0 to 1 M variable
Note: The adjuster (ADJUST) on the top of the Sensor
Amplifier sets the resistance for detection within
the setting range. It is factory-set to the upper
limit. (Normally, the K7L can be used with the
adjuster at this setting.)

Output
configuration
NPN open-collector transistor output with 100 mA at 30 VDC max.
for both liquid leakage detection and disconnection detection.
Note: If the rightmost pin of the DIP switch on the side of the
Sensor Amplifier is set to the down position, the output
turns ON when liquid is detected; if it is set to the up
position, the output turns OFF when liquid is detected.
