EMP10
FEATURES
10mm Enclosed Cermet
Preset Potentiometer
High dissipation metal-glaze resistive element on a
ceramic base. Insulated actuating device with hexagonal
slot or cross slot. Both sides suitable for actuating.
Horizontal adj. and vertical adj. versions. Adjustment by
means of insulated hexagonal or cross slots. Overall
width: 9,8 mm (allows for high density use with air-gap
isolation on a 2,5 mm grid). The glass-filled synthetic
resin housing is fire resistant. Stable high quality
performance.Can be mounted by automatic insertion
machines.

TYPICAL APPLICATIONS
Designed for video, audio and industrial applications and
especially suited for equipment in which automatic
adjustment is required. Versions with a hexagonal slot
are available with a knob to facilitate manual adjustment
TERMINAL DESIGNATION
Terminals a and c are the end terminals; b is the central
terminal connected to the wiper. All terminals are either
straight or snap-in pins for mounting on printed-wiring
boards of nominal 1,0 to 1,6 mm thickness, grid pitch 2,5
or 2,54 mm.
