Series

LKL-P2

Versions

probe with integrated electronic insert (compact instrument version) probe without integrated electronic insert (separate instrument version) for one, two or multiple point detection respectively, see section measuring system

Connection

see section electrical connection

Rated voltage

U r output E5 (FEW52): supply voltage 10.8 ... 45 V DC load connection: open collector; PNP switching voltage: max. 45 V output N1 (FEW58): refer to datasheet of the connected switch amplifier acc. to IEC 60947-5-6 (NAMUR)

Current consumption

output E5 (FEW52): I < 25 mA (without load)

Power consumption

output E5 (FEW52): P < 1.1 W

Reverse polarity protection

output E5 (FEW52)

Input signal

probes covered - A measurable current is flowing between the probes. probes uncovered - There is no measurable current flowing between the probes.

Measured variable

resistance change between two conductors caused by the presence or absence of a conductive product.

Measuring range

The measuring range depends on the mounting location of the device 100 ... 15000 mm

Switching delay

A switching delay of 2.0 s can be activated or deactivated via a DIL switch. If the switching delay is set to 0 s, the device switches after approx. 0.3 s.

Load

output E5 (FEW52): The load is switched via a transistor (PNP), cycled overload and short-circuit protection, continuous ≤ 200 mA (short-circuit proof), residual voltage at transistor at I max 2.9 V output N1 (FEW58): refer to datasheet of the connected switch amplifier acc. to IEC 60947-5-6 (NAMUR)

Output signal

see section electrical connection

Signal on alarm

output E5 (FEW52): in the event of a power failure or a damaged probe: < 100 µA output N1 (FEW58): output signal with damaged sensor < 1 mA
