A solenoid is an electromagnet which applies a straight-line force, in a push or pull motion, when energized.

A solenoid consists of a frame, plunger, and coil. When the coil is energized, a magnetic field is set up in the frame. This magnetic field causes the plunger to move into the frame. The result is a straightline force.

GE's CR127 industrial pressure switches are designed for pilot-duty applications in control systems of hydraulic and pneumatic equipment. The bellows actuated forms, used with low-pressure applications of air, water and most hydraulics, are applied primarily on machine tools and welding equipment. Piston actuated forms are designed for use with high-pressure hydraulics such as lubricating systems.

Both bellows and piston forms must be used within their maximum safe pressure range which should be greater than line pressure including pressure surges. Although the switches are furnished with an orifice to protect against minor surges, a surge reducer should be used for protection against greater line surges. Also, a customer ground connection is provided within the enclosure.

GE's CR115A30 and CR115A35—CR115A30 and CR115A35 general-purpose limit switches have similar characteristics and features as GE CR115A with the exception of 1/2-inch side slot and a larger mounting plate that has six mounting holes. The CR115A30 has one normally open contact and no indicating light. The GE CR115A35 has one normally closed contact and no indicating light.

GE's CR115AS—This oiltight and dust-tight, solid-state limit switch provides the high reliability and important long life of the GE CR115A. The switch's electrical rating makes it capable of handling high inductive loads. This model offers virtually unlimited operating life at significantly higher ratings.

GE's CR115A and GE's CR115AS provide accurate position detection of objects at distances up to 4 1/8 inches without physical contact. The switch is actuated by passage of a magnet near the face of the switch. This action causes the normally open contact to close and remain closed until the magnet is removed.

Magnet-operated GE limit switches are well-suited for controlling objects having an erratic motion such as skip hoists, elevators, and overhead conveyors.

GE's CR115AS solid-state limit switch is specifically designed for applications under severe conditions, and is oiltight, dust-tight and watertight.

GE's CR115E geared rotary limit switch provides limit control on rotating-drive equipment. This worm and gear-reduction limit switch may be used in conjunction with motors to open and close overhead doors, to operate cable on cranes and hoists, limit the number of turns on thread-tapping equipment, and on other machine tool applications that require rotating-drive shaft control.

GE Switches are provided in NEMA Type 1, 4, 7, and 9 enclosures for adapting to specific environmental conditions. Forms having longdwell cams may be ordered by description. Forms with various contact arrangements of snap-acting switches are listed.

GE CR115B Precision Snap-Acting Limit Switches are designed for rugged industrial use in a small space where highly repetitive operation is desired. These highly accurate switches require only a small amount of plunger travel to actuate.

One- and two-pole forms are available.

The basic switch is equipped with a button-type operator. Plunger-type forms are available for mounting behind the panel with only the button protruding. Roller lever forms are available for applications requiring a transfer of the axis of motion or for detection of objects passing the switch.

Typical applications include controlling solenoids, opening and closing valves, and controlling small horsepower motors.

GE's CR102 manual drum switches are used to stop, start, and reverse single-phase or inherently protected polyphase motors on small tools, hoists, and farm or commercial machinery up to two horsepower at a maximum of 600 volts. Forms are available to reconnect dual voltage motors; and to operate a motor in one direction and a solenoid in the other. The manual drum switch is the most economical device if your application does not require undervoltage or overload protection.

Three-phase CR102A forms may be used on single-phase motors providing one wire is connected directly to the motor. Single-phase CR102A forms may be used on three-phase motors providing one wire is connected directly to the motor.
