T9SPC - Nöjdhs Elektronik

Electrical System Design

We are involved in system and detail design down to cabinet level, as well as installation planning and set to work.

Power Electronics

Power electronic systems mainly for motor drives are designed upon customer specification.

Automation

We design and produce control systems for different applications, mostly for submarines and for the process industry.

Electronic Design

From single PCBs to entire systems. To minimize development time we use modern design and simulation tools.

Mechanical Design

Due to our experience from different defence projects we have developed a certain skill for packaging of electronics and equipment.

Maintenance and Repair

Mainly on our own products but also in general. Periodic maintenance is planned and conducted in cooperation with the customer.

The inductive proximity switch has been developed for contactless position sensing under water. The proximity switch works with all types of metal targets.

The proximity switch is tested for pressure, shock and EMC according to military requirements. As a standard the proximity switch is delivered with 2-meter screened cable but other length can be offered on request.

The inductive proximity switch consists of a sensor element which is mounted in a plastic housing. A cable specially designed for underwater use is connected to the sensor element. The housing is then molded so that the sensor element and the cable connection are fully surrounded by the molding compound. This ensures that no water will enter the sensor element or the connection area even if the housing should be damaged.

The main features are:

Pressure tested to 70 bar
Shock resistance tested to 2000g
Screened cable with concentric connection to sensor body
Ability to be activated against magnetic as well as non-magnetic materials

The proximity switch could be configured to suit various applications upon request. Please contact us for more details.
