Elesa+Ganter 11182 HCV.127-E-AX-NC-M12 Electrical Level Indicator

The Elesa+Ganter 11182 electrical level indicator, stock code HCV.127-E-AX-NC-M12, is a transparent technopolymer level indicator with a MIN level electrical sensor and normally closed contact configuration. This product type is used in hydraulic systems where visual inspection and electrical low-level detection are both required.

Technical Overview

The HCV.127-E-AX-NC-M12 is part of the HCV-E-AX series. The 127 size is suitable for many compact and medium hydraulic tanks, while the M12 connector allows straightforward integration into industrial control systems. The NC designation means normally closed contact. In many safety-focused designs, normally closed contacts are preferred because a change in circuit state can indicate either a low-level condition or, depending on the system logic, a wiring interruption that requires attention.

Visual and Electrical Monitoring

This indicator supports two layers of monitoring. First, the transparent column allows operators to visually confirm oil level during routine checks. Second, the electrical sensor can communicate a minimum level event to a control panel, alarm system, PLC, or machine monitoring circuit.

The Elesa+Ganter 11182 HCV.127-E-AX-NC-M12 electrical level indicator is therefore useful in applications where machine reliability, maintenance planning, and early warning signals are important.

Common Applications

This product type is commonly used in hydraulic power packs, industrial machinery, oil reservoirs, machine tools, automated equipment, lubrication systems, and process machinery. It is especially valuable where low fluid level could cause overheating, unstable pressure, pump wear, or production interruption.

Elesa+Ganter 11182 HCV.127-E-AX-NC-M12 FAQ

What is the Elesa+Ganter 11182 HCV.127-E-AX-NC-M12 used for?

It is used to monitor hydraulic oil level visually and electrically. The transparent indicator shows the fluid level, while the sensor provides a signal when the minimum level is reached.

What does NC mean in this product code?

NC means normally closed. This contact configuration is often used where the control system expects a closed circuit during normal operation and detects a change when the monitored condition occurs.

How is this different from the NO version?

The difference is the electrical contact logic. The NO version is normally open, while this NC version is normally closed. The correct choice depends on the control system design and safety logic.

Why choose an electrical level indicator instead of a basic visual indicator?

An electrical level indicator can send a signal to the machine control system. This is helpful when the equipment must alert operators automatically or stop operation before the oil level becomes critically low.

Is the M12 connection useful for industrial wiring?

Yes. M12 connectors are widely used in industrial automation because they are compact, secure, and practical for sensors and machine monitoring components.
