Latching Relay MMK
Caution
Product Description
A cost-effective industrial-use relay with a low power consumption.
[Features]
·Type MM power relay with a mechanical lock latching system.
·Mechanically holds the operations.
· Quick operation due to pulse transmitted electrical power.
·Wide operating temperature range from -10°C to +55°C.
·Models compliant with auxiliary power relays (JEC-174D) are also available.
[Applications]
·Ideal for motor and control operation switching.
