Contact devices
(limit switch contact assemblies)

Available: NG 63 to 2-fold | NG 100 to 4-fold | NG 160 to 4-fold

SNEAK CONTACTS

are used when no high contact load is required and no vibrations occur.

Technical data

Rated operating voltage: max. 250 V
Switch-on and switch-off current: max. 0,7 A
Switching capacity: 10 W 18 VA
Switching accuracy: approx. 0.5 % of the full scale value

MAGNETIC SPRING CONTACTS

can be used in almost all operating conditions and are largely insensitive to vibrations.

Technical data

Rated operating voltage: max. 250 V
Switch-on and switch-off current: max. 1.0 A
Switching capacity: 30 W 50 VA
Switching accuracy: approx. 2-5 % of full scale value

INDUCTIVE CONTACTS

are equipped with non-contact NAMUR proximity switches. They are particularly suitable for oil-filled measuring devices and can be used in potentially explosive atmospheres when using Ex-certified isolating switch amplifiers.

Technical data

Nominal voltage: 8 V DC
Switching accuracy: approx. 0.5 % of the full scale value

ELECTRONIC CONTACTS

are equipped with non-contact slot initiators. They are particularly suitable for oil-filled measuring devices and should be preferred for low voltages and small DC loads, e.g. for the signal input of a PLC.

Technical data

Operating voltage range: 10-30 V DC
Switching capacity: 100mA
Switching accuracy: approx. 0.5 % of the scale value

PNEUMATIC CONTACTS

are equipped with pneumatic slot initiators. They are used where air is already being used and/or where there is no electricity.

Technical data

Operating pressure: 1.4 bar
Pre-pressure: approx. 0.1 bar
Outlet pressure: approx. 30 mbar
Intrinsic air consumption: approx. 30 l/h

LIMIT SIGNAL ENCODER in modular system

All the above contacts can also be supplied in a modular system. To simplify installation, a mounting unit has been created that can be mounted on any measuring device in just a few minutes. This unit consists of a transparent cover, adjustable lock, cable gland or plug connection and a special contact with plug-in base and fork coupling.

Executions

Standard with PG cable gland or oil-tight with plug and cable, fully assembled and wired. Available are NG 100, NG 4 ½”, NG 6″, NG 160
