1. Amber sealed type
When mounting TM types, use washers
to prevent damage or distortion to the
polycarbonate cover. When tightening
fixing screws, the optimum torque range
should be 0.294 to 0.49 N·m, (3 to 5
kgf·cm). If screws are over tightened, the
cover may distort, resulting in poor
sealing. Moreover, to prevent loosening,
use washers.
2. Keep relay
1) The schematic differs from that in the
standard type 4 Form C HC relay. Follow
the schematic on the cover sticker.
2) Conform with the schematic for the DC
type, which has a polarized coil.
3) Because retention characteristics vary
according to the waveform of the voltage
applied to the coil, do your best to avoid
capacitor driving.
In capacitor driving, use a capacitor of
300 µF or more.
4) Ensure that the minimum pulse width
of voltage applied to coil is greater than
150 ms.
3. Diode characteristics
1) Reverse breakdown voltage: 1,000 V
2) Forward current: 1 A
4. Diode and CR built-in type
Since the diode and CR inside the relay
coil are designed to absorb the counter
emf, the element may be damaged if a
large surge, etc., is applied to the diode
and CR.
If there is the possibility of a large surge
voltage from the outside, please
implement measures to absorb it.
5. Please connect DC coil types with
LED and built-in diode correctly by
verifying the coil polarity (“+” and “–
”). Connecting with reverse polarity
will cause the LED not to light and
damage the built-in diode due to its
specification.
