Industrial Level Controller for Process Monitoring

The Turck MK91-12-R-24VDC is a rectangular level controller designed for industrial process monitoring and liquid level detection. It operates on a 10 to 65 VDC supply with a complementary PNP output function. The CP40 housing measures 114 by 40 by 40 mm and features a rated switching distance of 50 mm. The uprox+ factor 1 technology ensures consistent sensing across all metals.

Sealed IP68 Housing with Terminal Chamber

The PBT-GF30-V0 plastic housing achieves protection class IP68 for harsh environments. High luminance corner LEDs provide clear indication of supply voltage and switching state from any angle. The variable orientation of the active face in nine directions allows flexible mounting. The terminal chamber enables direct wiring without separate connectors. Auto-compensation protects against pre-attenuation and the unit resists magnetic field interference.

Replaces Basic Float or Capacitive Sensors

This controller upgrades from simple float switches or basic capacitive probes where metal detection consistency and magnetic immunity are required. The jump is worth it when an application demands factor 1 sensing on all metals, non-flush mounting flexibility and IP68 durability in a single 204 g package. It is not suited for buyers who need analog level measurement or continuous output signals.

Questions about this item

How do I mount the rectangular CP40 housing and orient the active face correctly?

Mount the 114 x 40 x 40 mm housing non-flush, then rotate the active face to one of the 9 directions before tightening to align the sensing field with the target.

What maintenance does the PBT-GF30-V0 housing and IP68 seal need over time?

Inspect the terminal chamber seals and housing surface for chemical damage or cracking; replace the unit if the IP68 integrity is compromised or the corner LEDs become unreadable.

At what point does the 10…65 VDC supply range limit continuous operation?

Operation stops if the DC supply falls below 10 V or exceeds 65 V; sustained voltage outside this window will cause the complementary PNP output to fail.
