Application

These actuator accessory kits are designed for

installation on MC, MF, MP, MU, and MUP type

oil-submerged gear train actuators. The accessory kits

are coupled to the rear of an actuator output shaft by

means of an interlocking drive disc.

Features

• Potentiometers provide accurate feedback of

actuator position for indication and precision control

• Adjustable differential SPDT auxiliary switches may

be adjusted to operate at any point in the actuator

stroke for maximum application flexibility

Potentiometer Adjustment Accessory kit AM-332 contains a potentiometer. This potentiometer consists of a spring-loaded, friction-driven, copper wiper arm with a contact that rides on a uniformly wound wire resistance card. The standard card has a resistance of 100 Ω, and is to be used only with a power supply which does not exceed 25 Vac. The electrical capacity of the resistance card is approximately 3 watts.
