The Siemens Pointek CLS200 is an RF capacitance point-level switch for detecting level, interfaces, and presence in liquids, solids, slurries, and foam. Designed for demanding process environments, the CLS200 uses radio frequency capacitance technology to detect material at a single setpoint, with adaptable sensitivity and the ability to tune out probe buildup, a critical feature in applications where coating or adhesion would otherwise cause false trips.
PLC Direct supplies Pointek CLS200 hardware to customers maintaining installed level detection systems in process and industrial facilities. Our collection covers Standard and Digital variants of rod-and-cable probe designs across multiple process connection sizes and hazardous-area approval configurations.
Where Siemens Pointek CLS200 Are Used
A failed point level switch in a vessel, silo, or tank can disable a high-level alarm, interrupt a pump control interlock, or force a manual monitoring workaround until the instrument is replaced. In facilities where the Pointek CLS200 is the installed instrument, replacing it with a different device often means reconfiguring the process connection, rewiring the output circuit, or re-establishing the sensitivity calibration for the specific process material. Sourcing an exact-match replacement avoids all of that.
Facilities and applications that depend on the Pointek CLS200 include:
- Bulk solids handling and storage silos requiring reliable level detection in dusty or adhesive materials
- Liquid process vessels in chemical and petrochemical plants where foam or coating on the probe is a recurring challenge
- Slurry and paste applications in mineral processing and pulp and paper facilities
- Pump protection and dry-run prevention circuits in liquid handling systems
- High- and low-level alarm circuits in tanks and vessels requiring hazardous area-rated instruments
- Interface detection applications where two liquids or a liquid/solid boundary must be identified
Siemens Pointek CLS200 Products
This collection covers Pointek CLS200 Standard and Digital variants across rod and cable probe designs, multiple process connection sizes, and a range of hazardous area approvals. All product families and part numbers below are confirmed on the live PLC Direct collection page.
Product Families
-
Pointek CLS200 Standard — Rod Probe Design: The CLS200 Standard uses an insertable rod probe with adjustable sensitivity up to 5.5 m (18.04 ft) insertion depth. Process connections are threaded 316L stainless steel in 3/4" NPT and 1-1/4" NPT configurations. Wetted seals are FKM. Enclosure is aluminum epoxy coated at IP65 or IP68, with 2x 1/2" NPT cable inlets via adapter. Confirmed variants in stock cover multiple probe length, material, and approval combinations:
- 7ML56300AA000HA0: 3/4" NPT, compact probe 120 mm, 316L SS / PPS body, General Purpose (CSA, FM), IP65
- 7ML56300AB001FA0: 3/4" NPT, extended rod 250 mm, 316L SS / PVDF body, Dust Ignition Proof with IS Probe (CSA/FM Class II, III Div.1 Gr.E, F, G T4), IP65
- 7ML56300CB000FA0: 1-1/4" NPT, extended rod 250 mm, 316L SS / PPS body, Dust Ignition Proof with IS Probe (CSA/FM Class II, III Div.1 Gr.E, F, G T4), IP65
- 7ML56300CE000FA0: 1-1/4" NPT, extended rod 750 mm, 316L SS / PPS body, Dust Ignition Proof with IS Probe (CSA/FM Class II, III Div.1 Gr.E, F, G T4), IP65
- 7ML56300CF000FA0: 1-1/4" NPT, extended rod 1000 mm, 316L SS / PPS body, Dust Ignition Proof with IS Probe (CSA/FM Class II, III Div.1 Gr.E, F, G T4), IP65
- 7ML56300CX000GC0: 1-1/4" NPT, 316L SS / PPS body, Explosion Proof with IS Probe (CSA/FM Class I, II, III Div.1 Gr.A–G T4), IP68
-
Pointek CLS200 Digital — Cable Probe Design: The CLS200 Digital adds a display and digital communications to the standard RF capacitance measurement, and uses a flexible cable probe extending up to 30 m (98.43 ft), suited to tall vessels or applications where a rigid rod probe is not practical. Probe material is FEP jacketed cable with PPS probe body. The cable length can be shortened on-site by the customer.
- 7ML5641-0AB00-0JA0: 3/4" NPT (ANSI/ASME B1.20.1), 316L SS, extended cable 6000 mm (field-shortenable), FKM and PTFE wetted seals, Explosion Proof with IS Probe (CSA/FM Class I, II, III Div.1 Gr.A–G T4), aluminum epoxy coated enclosure, IP65
All CLS200 variants carry active (PM300) lifecycle status.

What to Know Before You Buy Siemens Pointek CLS200
Replacing a CLS200 requires matching the process connection size, probe type and length, wetted material, hazardous area approval, and enclosure rating to the installed instrument. Each of these variables is encoded in the part number.
Hardware condition options: We supply Pointek CLS200 instruments as surplus sealed, refurbished, and used hardware. Surplus sealed units are factory-sealed stock. For process instruments with calibrated sensitivity settings, confirming the condition grade is worthwhile; refurbished units have been tested and verified for functionality.
Compatibility considerations: Rod probe and cable probe variants are not interchangeable in the same process connection. The probe length must be appropriate for the vessel geometry and the level setpoint. Hazardous area approval class (General Purpose, Dust Ignition Proof, or Explosion Proof) must match the area classification of the installation. FKM wetted seals are standard across the rod probe variants, confirm compatibility with the process fluid before ordering.
Part identification: The CLS200 part number encodes the product family (7ML5630 for Standard, 7ML5641 for Digital), the process connection size and type, the probe length, wetted seal and probe body materials, and the approval and enclosure configuration. When ordering a replacement, always use the full part number from the installed instrument's nameplate to confirm the correct variant.
Warranty: All Pointek CLS200 instruments purchased from PLC Direct include a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
