Elesa+Ganter 113305 HCK.127-SST-M12-NBR-PC-P-80-NO Column Level Indicator

The Elesa+Ganter 113305 HCK.127-SST-M12-NBR-PC-P-80-NO column level indicator is an industrial oil level monitoring component designed for hydraulic systems, lubrication reservoirs, and machinery that require a protected visual indicator with normally open electrical contact. It helps operators read fluid level directly while also supporting signal-based monitoring.

Technical Structure

This HCK.127 model has a 127 mm hole centre distance and M12 thread configuration. SST indicates stainless steel fastening hardware, while NBR refers to the sealing O-ring. The PC marking identifies the transparent polycarbonate tube, and the P code confirms the presence of removable front protection. Together, these details create a durable and service-friendly indicator for industrial oil applications.

Normally Open Contact

The NO contact configuration means the electrical contact is normally open until the switching condition is reached. This can be useful in control systems where the signal is required only when a defined level condition occurs. Depending on the machine design, the output may be used for warnings, panel indicators, or maintenance notifications.

Protected Design for Industrial Areas

The front polycarbonate protection helps defend the level tube from routine contact, dirt, and workshop exposure. This makes the Elesa+Ganter 113305 HCK.127-SST-M12-NBR-PC-P-80-NO oil level indicator suitable for machine panels, hydraulic power units, production equipment, and other systems where clear visibility and component protection are both important.

Why It Matters in Maintenance

Oil level monitoring is a small but critical part of machine reliability. Low oil levels can increase wear, reduce cooling, and create operating instability. A protected column level indicator with electrical contact gives maintenance teams a fast visual reference and a practical signal point for system supervision.

FAQ

What does NO mean in this model?

NO means normally open contact. The electrical circuit remains open under normal conditions and changes state when the defined level condition activates the sensor.

How is 113305 different from 113303?

The key difference is contact type. The 113305 version uses NO contact, while the 113303 version uses NC contact. Both are protected HCK.127 oil level indicators.

Does this model include front protection?

Yes. The “P” code means the transparent tube has removable polycarbonate front protection, helping improve durability in industrial environments.

Where can this indicator be installed?

It can be installed on hydraulic reservoirs, oil tanks, lubrication units, machine tools, and industrial systems that require visual oil level indication and electrical status feedback.
