Contact arrangement: 1 Form U (Form A)
Voltages: standard coil voltages of 9 Vdc, 10 Vdc and 12 Vdc
Coil power consumption: 860 mW at rated coil voltage
Operating temperature range: -40ºC to +125ºC
Operating life: a mechanical life expectancy of 10 million operations and an electrical life of 100,000 operations
Packaging: 5.5 mm (L) x 12.2 mm (W) x 13.7 mm (H), surface-mount compatible
Weight: Approx. 6 g
RoHS compliant? constructed of lead-free materials and meets environmental disposal program requirements
Target applications: automotive, commercial and recreational vehicles
