Elesa+Ganter 111111 HCY.127-E-NO-M12 Column Level Indicator

The Elesa+Ganter 111111 HCY.127-E-NO-M12 column level indicator is designed for visual oil level monitoring in hydraulic reservoirs, with an integrated minimum level electrical sensor. It is a practical component for maintenance teams, machine builders, and hydraulic system designers who need both clear level visibility and a signal when oil reaches a critical low point.

Technical Overview

This model belongs to the HCY-E series and features a 127 mm centre distance with an M12 thread connection. The NO version uses a normally open contact, meaning the electrical contact closes when the minimum oil level is reached. This makes it suitable for warning circuits, alarm panels, or machine monitoring systems where a low-level event must trigger an input.

The body is made from technopolymer and is intended for hydraulic oil applications. Its maximum continuous working temperature is 80°C with oil. In laboratory testing with mineral oil CB68 at 23°C, the HCY.127 size withstands up to 9 bar for a limited period. The white contrast screen improves reading clarity and can help operators check oil level quickly during routine inspections.

Where It Is Used

The Elesa+Ganter 111111 HCY.127-E-NO-M12 column level indicator is commonly used on hydraulic power units, lubrication tanks, compact industrial machines, and equipment where space-efficient level monitoring is required. Its electrical output supports preventive maintenance by helping detect low oil level before pump cavitation, overheating, or unexpected downtime occurs.

Elesa+Ganter 111111 HCY.127-E-NO-M12 Level Indicator FAQ

What does NO mean on HCY.127-E-NO-M12?

NO means normally open. In this model, the contact closes when the minimum level is reached, allowing the system to send a low-level signal.

Is this indicator only for visual checking?

No. It provides visual oil level monitoring and also includes an electrical minimum level sensor for automated machine feedback.

What is the mounting size?

The product has a 127 mm mounting centre distance and an M12 thread connection.

Can it be used near magnetic fields?

It should not be mounted close to magnetic fields, as this may affect sensor operation.
