LOW-ACTION contacts

are used in the absence of high contact loads and vibrations.

Technical Data

Nominal operating voltage: max. 250 V

Making and breaking current: max. 0,7 A

Breaking capacity:
10 W 18 VA

Switching precision: approx. 0,5 % of final scale value

SNAP-ACTION contacts

can be used under almost all operating conditions and are partially not affected by vibrations.

Technical Data

Nominal operating voltage: max. 250 V

Making and breaking current: max. 1,0 A

Breaking capacity:
30 W 50 VA

Switching precision: approx. 2-5 % of final scale value

Technical data sheets

INDUCTIVE-contacts

are equipped with non touching proximity NAMUR switches. They should be preferable used with oil filled measuring instruments. With an ex-prooved isolating amplifier they can be used in explosion proof areas.

Technical Data

Rated voltage: 8 V DC

Switching precision: approx. 0,5 % of final scale value

ELECTRONIC-contacts

are equipped with non touching proximity switches. They should be preferable used with oil filled measuring instruments, for operating under low voltages and for small DC-loads, eg. for direct connection to a PLC.

Technical Data

Operating voltage:
10-30 V DC

Breaking capacity: < 100mA

Switching precision: approx. 0,5% of final scale value

PNEUMATIC-contacts

are equipped with with pneumatic slot sensors. They are used where compressed air is readily available, and/or electric current is lacking.

Technical Data

Operating pressure: 1,4 bar

Admission pressure: approx. 0,1 bar

Outlet pressure: approx.
30 mbar

Internal air consumption: approx. 30l/h

LIMIT VALUE SWITCHES in a modular system

All before mentioned contacts are likewise available in a modular system. To simplify mounting of contacts onto the dial of instruments, we have developed an add-on unit which can be fitted to any measuring instrument within minutes.

The add-on unit consists of a transparent hood, an adjusting lock, cable gland or plug respectively, and a special contact with a plug base and fork coupling.

Models

standard with PG cable gland or oiltight with plug and cable, completely mounted and wired.

Available in DN 100,
DN 4 ½ ", DN 6", DN 160
