*Specifications will vary with foreign standards certification ratings.

*1	Measurement at same location as "Initial breakdown voltage" section
*2	Min. 500MΩ at 100 V DC between coils of 2 coil latching type
*3	Detection current: 10mA, Except for between coils of 2 coil latching type

*6	Half-wave pulse of sine wave: 6ms
*7	Detection time: 10µs
*8	Although NR relays are rated at 10 G/55 cps. vibration resistance, they will with-
	stand up to 60 G/2,000 cps., provided they receive additional support such as
	anchoring to the PC board with epoxy resin.
*9	Refer to 5. Conditions for operation, transport and storage mentioned in
	AMBIENT ENVIRONMENT (Page 61)
*10	Total temperature (ambient temperature plus temperature rise in coil) should not
	exceed 90°C 194°F for single side stable, and 105°C 221°F for latching relays.

Structure

	Contact arrangement	1 Form C	1 Form A or 1 Form B
	Contact capacity	20 W (high contact pressure)	5 to 15 W
	Operating function	Single side stable	Single side stable
		Latching
	"Getter" hole	Yes	No

"Getter" holes are formed on both pole shoes to obtain uniform contact resistance throughout life. Film-forming phenomena on contacts is thus fully prevented.
