Description:
The contamination switch series EY-1356
works as a warning element in hydraulic
systems and gearboxes and has been
developed by HYDAC ELECTRONIC
to meet the special requirements of our
customers.
The sensor detects and attracts metallic
ferromagnetic particles in oil or in other
hydraulic uids. The accumulation of
particles leads to a change of the ohmic
resistance which has an effect on the
switching signal. The contamination sensor
thus provides an early warning of possible
wear. Substantial damage on bearings and
gear wheels, for instance, can therefore be
avoided.
The sensor is available with different
mechanical and electrical connections
and can be integrated into almost any
application.
Special features:
●
Simple structure
●
Robust construction
●
Standard connection types
Functional principle /
diagram:
The permanent magnet solenoid at the
measuring surface of the contamination
switch attracts the ferromagnetic contaminant
particles from the passing oil. The increased
accumulation of particles forms an electrical
bridge between the permanent solenoid and
the adjacent metal contact. The resulting
switching signal can, for instance, activate a
warning function or switch off the system.
Technical data:
Maximum switching voltage 30 V DC
Maximum switching current 200 mA
Maximum oil pressure abs. 6 bar (16 bar)
Retention force of the permanent solenoid ~ 1.5 N
Ambient temperature -25 °C to +90 °C
