Mechanical pressure switches

Mechanical pressure switches convert fluid pressure into mechanical movement, and are a cost-effective and reliable solution used in a range of applications, especially in switching high currents such as those in pumps and drives.

The Bosch Rexroth range of mechanical pressure switches caters for both low demand (few switching cycles) and high demand (frequent switching cycles). Switches have a pre-set or configurable mechanical adjustment of the switch point.

Use a mechanical pressure switch in single-switch contact applications, and in safety critical applications as a redundant component, instantly kicking into action when pressure crosses a critical, pre-set point.

Bosch Rexroth mechanical pressure switches offer a range of features, including optional leakage ports, control lamps, lockable rotary knobs and micro switches with NC/NO contact function. Electrical connections include cable gland, plug-in or large cubic connectors.

Electronic pressure switches

These pressure switches are used in applications requiring an electronic output signal. They provide more control configurability than mechanical switches with an integrated programmable logic, so switch points and output signal can be defined according to your application requirements.

A wide range of functions, including delay time, switch point, reset switch point, hysteresis or window function can be programmed with Bosch Rexroth electronic pressure switches.

The electronic pressure switch is used in applications with multiple switch points and where control flexibility is required.

Bosch Rexroth electronic pressure switches feature compact designs, stainless steel and FKM media contacts, two antivalent switching outputs (or one switching output and one analogue output), electrical connection via 4-pole M12 connector and sensor thin film measuring cells.
