CSM_G7SB_DS_E_3_1
Low Profile Relays with Low Power
Consumption
• Relays with forcibly guided contacts
(EN50205 Class A, certified by VDE).
• Low profile - only 14.5 mm.
• Coil power consumption is 360 mW for 4 pole model or
500 mW for 6 pole model.
• Four-pole and six-pole Relays are available.
• The Relay's terminal arrangement simplifies PWB pattern
design.
• Reinforced insulation.
Be sure to read the “Safety Precautions” on page 4 and the
“Precautions for All Relays with Forcibly Guided Contacts”.

Note: The above values are initial values.
*1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
*2. These times were measured at the rated voltage and an ambient temperature of 23°C. Contact bounce time is not included.
*3. The response time is the time it takes for the normally open contacts to open after the coil voltage is turned OFF. Contact bounce time is
included. Measurement conditions: Rated voltage operation, Ambient temperature: 23°C
*4. The insulation resistance was measured with a 500-VDC megohmmeter at the same locations as the dielectric strength was measured.
*5. Pole 3 refers to terminals 33−34, pole 4 refers to terminals 43−44, pole 5 refers to terminals 53−54, and pole 6 refers to terminals
63−64.
*6. The durability is for an ambient temperature of 15 to 35°C and an ambient humidity of 25% to 75%.
*7. The failure rate is based on an operating frequency of 300 operations/min.
*8. When operating at a temperature between 70 and 85°C, reduce the rated carry current (6 A at 70°C or less) by 0.1 A for each degree above 70°C.

If an NO contact becomes welded, all NC contacts will maintain a
minimum distance of 0.5 mm when the coil is not energized. Likewise
if an NC contact becomes welded, all NO contacts will maintain a
minimum distance of 0.5 mm when the coil is energized.
