OMRON MM4K Product information and technical parameters:
Brand: OMRON
Name: Latching Relay
Model: MM4K
Type: Standard.
Contact form: 4PDT.
Open structure: Solder terminals.
Mechanically Latching Relays Based on the.
MM Power Relay.
Low power consumption due to mechanical latch for economic operation.
Relays with mixed coil specifications can be produced,
(e.g., AC setcoil and DC reset coil).
Operational response fast enough to enable pulse signal power applications.
Ambient operating temperature: –10°C to 55°C.

No. of steps: 12.
Rated voltage: 24 VDC, 100 VAC, 200 VAC.
Ideal for Controlling Pumps and Production.
Lines with Six or Twelve Stepping Circuits.
Built-in relays switch 2 A at 250 VAC or 30 VDC.
Initialization of stepping with reset input.
Uses memory that stores setting status for 10 days without MM4K.
power. All internal contacts are released when no power is supplied.
Detects an internal element malfunction caused by external MM4K
noise, indicates the malfunction with an alarm indicator, and,
turns the relay alarm output ON. (An internal relay malfunction,
or internal relay contact weld cannot be detected.).
With safety-design terminals which prevent electric shock accidents.
With easy-to-see indicators which display the stepping status MM4K. Contact form: SPST-NO.
Type: Models with Test Button and Built-in Operation Indicators.
Rated voltage: AC: 24, 100, 110, 120, 200, 220, 230, 240;
DC: 12, 24, 48, 110, 220.
MK-S-series Relays with DC-switching,
Models That Can Switch 220 VDC, 10 A,
(Resistive Load).
Switch a DC load of 220 VDC, 10 A (resistive load).
Models for AC Loads can switch 250 VAC, 15 A (resistive load) MM4K.
Lineup includes models with SPST-NO and SPST-NO/SPST,
NC contact forms.
Using a SPST-NO/SPST-NC contact form enables detecting,
contact welding. (When the NO contacts become welded, the,
NC contacts will maintain a minimum distance of 0.5 mm.).
Models available with operation indicators and built-in test buttons.
RoHS compliant.
Standards: UL, IEC (TÜV certification). Terminal (Wire connection): Push-In Plus Terminal.
Classification: Microloads.
Latching lever (Test switch): No.
Rated input voltage: AC, 110V.
Global standard size, low profile slim.
I/O relay with width 6.2 mm.
Realized about 25% lower profile than conventional.
products, contributing to further miniaturization of the control panel.
Realized opening and closing ability with one pole 6 A slim shape.
Micro load products for one pole 50 mA using Au-plated MM4K.
contacts for small load switching also available.
Since G2RV is a transparent case, confirming the state of,
the contact with the naked eye is possible, and easy to,
confirm abnormality on-site (installed locatiion) MM4K.
Screw terminal is also stocked to meet the screw type needs.
Mounted relay uses plug-in terminals that are difficult to,
bend when exchanging.
