SERIES
The series 40 contains capacitive 2-wire proximity signal Generators according to NAMUR DIN 60947-5-6, also StEx-Versions for use in zone 20 (dust explosion protection). These Sensors can be mounted in explosion hazardous areas when they are connected to approved isolating switching Amplifiers with intrinsically safe control circuit [EExia] or [EExib], our series N-131. Depending on the isolating switching amplifier selected the NAMUR-sensors of this series can be used up to zone 1 (StEx-Versions also for zone 20). The data specified in the certificate of conformity of the selected isolating switching amplifier must be taken into consideration. The 2-wire Analog Sensors of this series can also be used in zone 1 if they are connected to a ATEX-certificated amplifier, such as our series N-131-...

The transistor amplifier of our series 120 has been designed especially for use with our capacitive NAMUR mini-sensors (e.g. KAS-40-6/15-N, KAS-40-A11-N, KAS-40-18/5-N ). All sensors according to NAMUR are connectable (provided that the cable diameter corresponds to the connector), our series IAS-30... and KAS-40... The sensing distance is adjustable by means of a potentiometer, this also applies to Capacitive sensors that have no adjustment on the body. The antivalent outputs (NO and NC function) are overload protected and are available as pnp or npn output. The strong PA 6.6 housing may be mounted with additional units side by side and is equipped with a two- colour LED display that monitors stand-by (green) operating condition (yellow). Sensor and amplifier may be connected by a plug contact (female connector is enclosed).

The series 70 contains capacitive 3-wire or 4-wire Proximity sensors with NPN digital output with NO, NC or antivalent function (NO and NC). Electronic circuits, PLC‘s, Relays and our Power supplies of series 130 can be activated directly. The sensors are reverse-polarity protected, overload-protected and have electronic short-circuit protection. StEx-versions for applications in zone 20, sensors for ambient temperatures up to +100°C or for products with very high static charge complete the scope of the standard versions.

The series 80 contains capacitive 3-wire or 4-wire proximity sensors with PNP digital output with NO, NC or antivalent function (NO and NC). Electronic circuits, PLC‘s, relays and our power supplies of series 130 can be activated directly. The sensors are reverse-polarity protected, overload-protected and have electronic short-circuit protection. StEx-versions for applications in zone 20, sensors for ambient temperatures up to +100°C or for products with very high static charge complete the scope of the standard versions.

The series 90 contains capacitive 2-wire AC proximity sensors with thyristor digital output or FET-stage with NO and NC function. AC relays, conductors and solenoid Valves can be directly activated. PLCs with AC inputs can also be connected so long as the minimum load current is taken into consideration. The sensors have a protective circuit against high induction voltages.

The series 1000 duo~2 contains capacitive 2-wire a.c.-d.c. proximity sensors with NO and NC-function. The supply voltage range of 20...250 V AC/DC allows for applications in electronic circuits, PLC‘s as well as for conductors with AC supply voltage. The output functions (NO or NC) can be determined by means of a coding switch.

The series 2000 quattro+3 contains capacitive 3-wire DC proximity sensors with four output-functions, NPN-NO and PNP-NC or, after resetting of the coding switch, NPN-NC and PNP-NO. Electronic circuits, PLC‘s, relays and our power supplies of series 130 can be directly activated. Different housing materials are available, such as PA, PTFE, PTFE/brass or PTFE/V2A. This series is completed by a version for medium temperatures up to +160°C.
