Product catalog summary
General Specifications:
The document provides detailed specifications for various pressure switches used in industrial applications. These switches are designed for use with air or neutral gases, with options for lubricated or non-lubricated fluids. The pressure setting ranges from 0.5 to 10 bar, with a maximum allowable pressure of up to 16 bar. Operating temperatures range from -10°C to +60°C, and the devices are rated for a maximum voltage of 250V and a current breaking capacity of 5A at 250V resistive.
Construction and Design:
The pressure switches are constructed with materials such as Grivory (PA61/XT) and aluminum for the body, and Nitrile (NBR) for sealings. They feature a mechanical service life of up to 5 million contacts and can be mounted in any position. The switches include a pressure set screw and lock-nut for adjustments.
Electrical Characteristics:
The switches support a maximum switched voltage of 48 V DC and a current of 0.5 A. They are equipped with plated silver electric contacts and offer protection up to IP65. The devices also include integrated interference blanking and status indicators via diodes.
Dimensions and Weight:
The weight of the devices varies, with some models weighing 110 grams and others 180 grams. Dimensions are provided for different models, including details on mounting holes and connector sizes.
Additional Features:
Some models include digital displays with hysteresis and comparator functions, offering adjustable outputs and response times. The devices are designed to withstand vibrations and shocks, with specific resistance ratings provided.
Accessories:
The document lists available accessories such as bracket mounting kits and connectors, with specific catalogue numbers for ordering.
