Model 64
Vishay Spectrol
3/8” Square (10mm)
Multiturn Cermet Trimmer
FEATURES
• Unique Ratchet Device Integral with Gear to Ensure
Long Term Reliability
• Central Pivot Locating the Gear for Improved Stability
• I.C. Style Pins for Easy PCB Insertion
• Rigid Board Mounting Achieved with Pins Secured in
Housing
• Soldered Terminations for High Reliability
• Multifinger Precious Metal Wiper For Long Term Set
Point Stability
• Double Chevron Shaft for Sealing Plus Consistant
Torque and Reliable Adjustability
• Flame Retardent Plastic Housing
The Model 64 cermet trimmer from Vishay Spectrol incorporate improved design features making it one of the most ad-
vanced components of its type available in Europe. Giving maximum versatility with a choice of five pin styles and top or
side adjustment. Available from 10Ω to 2MΩ, the Model 64 has 25 turns nominal travel and a resistance tolerance of
± 10%. Significant design features include the use of two Chevron sealing rings on the shaft, for more consistent torque and
improved adjustability and flame retardant housing. A precious metal wiper significantly improves long term stability, making
it particularly suitable for telecommunication applications.
