–– -40˚F to 150˚F
Terminations
–– Contacts: 5/16"-24 UNF-2A thread
–– Coil: #10-32 UNF-2A thread
Recommended mounting
–– Contact Terminal: 60 inch-lbs., max.
–– Coil Terminal: 12-18 inch lbs.
––
caution: A back-up wrench must be used to hold the bottom
nut stationary
Type 124 custom Design capabilities
–– Vertical plane with coil terminals up.
–– Coil voltages 6 VDC through 48 VDC
–– High vibration
–– Gold plated contacts for pilot duty (low load switching) applications
–– Please complete application data form on page 95 of this section.
note:
caution must be used in coil selection for use in 12 volt systems where battery charging may expose coil to continuous,
higher-than-rated voltage. stancor will not be responsible for consequences of misapplied solenoids.
