Elesa+Ganter 113657-KN HCK.127-A4-M12-NBR-GL-P-E-SW-KN Oil Level Indicator

The Elesa+Ganter 113657-KN HCK.127-A4-M12-NBR-GL-P-E-SW-KN oil level indicator is a compact electrical column level indicator designed for hydraulic and industrial fluid reservoirs. It combines visual inspection with an electrical changeover contact, making it suitable for machinery where level monitoring must be both readable and signal-ready.

Construction Details

This model is built with A4 stainless steel fixing hardware, NBR sealing, a transparent borosilicate glass tube and a removable transparent polycarbonate guard. The 127 mm centre distance makes it practical for compact tanks, while the M12 mounting format supports standardized installation. The GL tube improves chemical and thermal suitability compared with basic plastic-only viewing solutions.

Changeover Contact Function

The E-SW-KN configuration provides changeover contact functionality through a 4-pole male M12x1 connector. This makes the unit particularly useful when a control system needs flexible wiring logic. A single level event can be routed as an alarm, interlock or monitoring signal depending on the electrical design of the machine.

Operational Value

In real maintenance routines, a visible level column helps technicians make quick decisions without opening the tank. The electrical contact adds a second layer of protection by helping detect abnormal level changes. This is especially valuable in hydraulic systems where insufficient oil can lead to overheating, pump wear, cavitation or unexpected downtime.
