Linear Limit Switches

(182 companies)
Linear limit switches are electromechanical devices that require physical contact between a target object and switch activator to make the contacts change state.

Vacuum Switches

(100 companies)
Vacuum switches are a type of pressure switch that functions in the vacuum end of the pressure spectra. They measure vacuum pressure (negative pressure).

IC Signal Generators

(41 companies)
IC waveform generators provide several different waveforms or functions at the desired frequency.

Rotary Limit Switches

(154 companies)
Rotary limit switches use physically-actuated levers to rotate a shaft and operate the contacts in a switch, making them change state. Most products feature a rugged design and are suitable for factory and/or industrial applications; however, because these switches contain mechanical parts, they wear over time. Typically, rotary limit switches are slower than noncontact, electrical devices such as proximity sensors and photoelectric sensors.

Liquid Level Switches

(411 companies)
Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action.

Limit Switches

(446 companies)
Limit switches are electromechanical or solid state devices that require the physical contact of an object with the switch 's actuator to make the contacts change state.

Diacs are bi-directional diodes that switch AC voltages and trigger silicon controlled rectifiers (SCRs) and triacs. Except for a small leakage current, diacs do not conduct until the breakover voltage is reached.
Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil.
Pneumatic relays and volume boosters control output air flow and pressure in response to a pneumatic input signal. They can perform simple functions such as boosting or scaling the output, or use complex reversal, biasing, and math function operators.

Switching Power Supplies

(294 companies)
Switching power supplies are DC sources that use a switching element (normally a power transistor) to generate the desired voltage. Switching power supplies are also called switch-mode products or switching mode power supplies (SMPS).

Solid State Relays

(612 companies)
Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications.
Volumetric liquid flow switches measure the flow or quantity of a moving fluid in terms of a unit of volume per time, such as liters per minute. These flow sensing devices have a switch output.

RTD Temperature Probes

(430 companies)
RTD (resistive thermal device) temperature probes are types of thermal resistors which measure temperature as a function of resistance.
Volumetric gas flow switches are devices with a switch output used for measuring the flow or quantity of a moving gas in terms of a unit of volume per unit time, such as cubic feet per minute.
...are non-contact proximity devices that are used to detect magnetic objects (e.g. permanent magnets). They sense the presence of a magnetic object, commonly referred to as the target. The target, characterized by its magnetic field, triggers the switching process...
