Elesa+Ganter 111172 HCY.254-E-ST-NC-M12 Oil Electrical Level Indicator
The Elesa+Ganter 111172 oil electrical level indicator is designed for hydraulic systems where visual oil level reading and electrical monitoring are both important. Identified by the stock code HCY.254-E-ST-NC-M12, this component supports reliable observation of oil level while providing a normally closed electrical contact for minimum level detection.
Technical Overview
This HCY-E-ST series indicator is manufactured from transparent polyamide-based technopolymer, a material selected for resistance to shocks, oils with additives, solvents, hydrocarbons and phosphoric esters. The unit includes nickel-plated brass screws, NBR synthetic rubber O-rings and a red technopolymer float with an internal magnetic element. When the oil level reaches the minimum threshold, the sensor generates an electrical signal.
The NC contact configuration means the circuit opens when the minimum oil level is reached. This is especially useful in applications where a break in continuity can trigger a warning, stop sequence or maintenance signal. The model also includes a MAX temperature electrical sensor set at 80°C, helping operators monitor both fluid level and overheating risk from one compact indicator.
Elesa+Ganter 111172 Where It Is Used
The Elesa+Ganter 111172 HCY.254-E-ST-NC-M12 oil electrical level indicator is suitable for hydraulic reservoirs, lubrication units, machine tools, industrial power packs and equipment where oil visibility and signal-based monitoring are required. Its IP65 connector protection supports installation in demanding industrial environments where water spray and contamination may be present.
Installation and Practical Notes
The indicator should not be installed close to magnetic fields because the float uses a magnetic element to activate the electrical contact. Alcohol-based detergents should also be avoided when cleaning the transparent body. For more product context, visit Elesa+Ganter components.
Elesa+Ganter 111172 FAQ
What is the main function of the HCY.254-E-ST-NC-M12?
It provides visual oil level checking, minimum oil level electrical signalling and maximum temperature monitoring in one oil level indicator.
What does NC mean on this model?
NC means normally closed. The electrical contact opens when the minimum oil level is reached, allowing the system to detect a low-level condition.
Is this indicator suitable for hydraulic oil?
Yes. It is intended for oil level monitoring in hydraulic systems, especially where mineral oil and industrial lubricants are used under compatible operating conditions.
What temperature does the sensor monitor?
The MAX temperature sensor is set to 80°C, giving the system a signal when the fluid reaches that threshold.
Why is transparent technopolymer used?
Transparent technopolymer allows clear visual reading while offering good resistance to impact, oils, solvents and common industrial fluids.
