Symbol
Current to coil
• Current flowing through coil generates
Solenoid
electromagnetic force to operate
plungers.
• Known as a semiconductor rectifier,
Diode
the diode allows current flow in one
direction only.
Cathode(K)
• A diode that lights when current flows.
Light-emitting
• Unlike ordinary bulbs, the diode does
diode
not generate heat when lit.
(LED)
• Allows current to flow in one direction
Reference diode
up to a certain voltage; allows current
(Zener diode)
to flow in the other direction once that
voltage is exceeded.
• The wiring position can be exchanged freely within the
connector.
• The wiring position can be exchanged according to the
following combinations only.
Between A and B, Between C and D, Between E and F
• The wiring position can be exchanged according to the
following combinations only.
Between 1, 2, 4 and 7.
• The wiring positions may be indicated by numbers for some
connectors.
