Less intrusion into the process
A short sensing tip suits compact vessels and pipes. Check insertion depth, nozzle geometry and cleaning access.

Compact electronic point level switches with PEEK sensing tips. Specify output, connection and process conditions for a configured quotation.
Request the process adapter, seal, M12 cable and electrical interface with the sensor. Confirm every supplied item in the quotation; accessories and certificates are not automatically included.
| Parameter | Reference value |
|---|---|
| Supply voltage | 12–30 V DC |
| Switching output | PNP / NPN |
| Maximum output current | 20 mA |
| Process temperature | −40…+115 °C |
| Process pressure | −0.1…10 MPa (−1…100 bar) |
| Wetted materials | PEEK + 316L / Ti (Option dependent) |
| Ingress protection | IP67 |
| Process connection | G ½ (Standard configuration) |
| Electrical connection | M12 · 4-pin |
| Sensing position tolerance | ±5 mm |
Values follow the supplied Lisen manual dated 2024-11-25. High-temperature versions up to 200 °C and custom probes up to 250 mm require separate confirmation. Maximum temperature and pressure must not be combined without an approved operating envelope.
Electrical reference from the supplied manual
The manual states a typical supply current of 8 mA and a maximum of 40 mA. This is separate from the 20 mA maximum switching load. A PLC input or a suitably designed interface is required; the sensor must not drive a pump motor or solenoid directly.
Configuration review
The source manual identifies a G½ connection, M12 four-pin connector and a nominal 99 mm overall drawing length. A high-temperature construction, extended probe, titanium wetted part or alternative process connection is a separate configuration. Request its drawing and simultaneous pressure/temperature limits with the offer.
The supplied material reports are supporting records, not blanket certification of every assembled sensor. Ask for batch traceability and destination-specific documentation where needed.
Technology comparison
Small sensing tip. A considered engineering choice.
A compact sensing tip and no moving float can simplify installation. Performance still depends on the medium, mounting position and settings.
Match the signal to the medium
Evaluate product, foam and residue separately. Difficult media may need a sample test and adjusted switching thresholds.
Build the complete sensor package
Confirm the sensor, mounting adapter, seal, cable and PLC input together. A matching thread alone does not ensure interchangeability.
