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.)

function

Detection signal: 10 VDC max., 200 ms

Detection time: 10 s max.

Recovery: Operation is recovered by resetting the power supply.

105% min. of operate resistance

Output

configuration

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.

These values are possible on the condition that a

completely insulated 3-conductor VCT cable with a

thickness of 0.75 mm

and a dielectric strength of 600 V

is used together with the Liquid Sensing Band specified

by OMRON. (A 0.2-mm

cable can also be used.)
