25A MicroRelays
General purpose: MicroRelays fit
many vehicles and applications.
Typical uses include: lamp control;
horns; power windows; fuel pumps;
fans; lift gates.
Smaller than regular relays, yet
MicroRelays can accept a load of
25A at 12V DC.
Standard terminal footprint for Form
A (SPST), Form C changeover (SPDT).
Sealed or unsealed.
Specifications:
• Contact rating (Resistive load) at 20°C:
12V DC: Normally Open 25A, Normally Closed 20A.
24V DC: Normally Open 15A, Normally Closed 10A.
Cole Hersee Relays are rated based on a steady
state resistive load. De-rate according to the type
of load:
• Contact arrangement: Available as Form A (SPST),
and Form C (SPDT).
• Motor load: Inrush can be 5 to 10 x steady state
current.
• Vibration resistance: 10-40Hz double amplitude
1.27mm.
• Solenoid load: Inrush can be 10 to 20 x steady
state current.
• Pull-in voltage: 7.8V maximum at 12V DC, 15.6V at
24V DC. Release voltage: 1.2V minimum at 12V DC,
2.4V at 24V DC.
• Incandescent lamp load: Inrush can be 10 to
15 x steady state current.
• Temperature range: -40°C to 85°C.
MicroRelays are also available with PCB
terminals:contact Cole Hersee.
• Operational life: Electrical to 100,000 cycles.
Mechanical to 10 million cycles.
• Contact Material: Silver alloy.
• Dielectric strength: 500V rms between coil and
contact.
• Insulation resistance: 100M minimum (500V DC).
