Profile

Proximon Controls Pvt. Ltd., an established name today in the automation products industry, has a legacy of 16 long years of quality output. It started with manufacturing of Inductive Proximity Sensors, Capacitive Proximity Sensors, Photoelectric Sensors & Color Mark sensors, multifunction counters and indicators. Subsequently, Logic Controllers for Packaging Machines were added in the product range.

The company’s philosophy has always been to make available High Quality Automation Products to the Indian Users at reasonable prices. As an extension of this endeavour, Proximon brought Precision Encoders & Counting Systems of Hengstler, Germany to the Indian market in the year 2000.

The long felt need of Indian OEMS, of an Indigenous Reliable SMPS at attractive prices was fulfilled by the company with its Marathon series SMPS. Today, it is the only company that manufactures Indigenous SMPS with CE compliance.

All these products are manufactured at the company’s state-of-the-art modern manufacturing facility at Navi Mumbai. A fully equipped design & engineering facility caters to customized solutions for OEMS.

• Inductive-Capacitive Sensors
• Proximity Photoelectric Switch
• Switch Mode Power Supply (SMPS)
• Logic Controllers
• Encoder
• Counter and Indicator

Proximon’s head office is situated at Thane, a developed Industrial & trade sector near Mumbai. The factory is situated in Navi Mumbai, which provides close communication & co-ordination between sales office and production units.

To compliment the marketing force, Proximon has established a country wide network of qualified resident engineers & experienced dealers at Ahmedabad, Aurangabad, Bangalore, Bilaspur, Chennai, Coimbatore, Chandigarh, Delhi, Dewas, Hyderabad, Indore, Jaipur, Kota, Kolkata, Kolhapur, Ludhiana, Nashik, Pune, Rajkot, Raipur, Surat, Vadodara, and many other places throughout the country.

A team of qualified engineers & technicians constitute our core manufacturing unit. Although, a vendor is selected after close scrutiny as per our standard assessment procedure, each incoming component is thoroughly tested as per quality manual, with the help of test equipments. A few testing jigs are developed in-house to facilitate efficient testing & remove non-conforming products at the incoming stage itself. After vigilant in-process quality control, the finished products like Inductive Proximity Sensors, multifunction counters and indicators etc. are again subjected to quality tests as required.

The details on Quality Control & Assurance System adopted in Proximon is also enclosed. The number of repeat orders and the status of preferred supplier that we have achieved today, are the result of our technical expertise and endless efforts to improve and maintain the quality of our products. The turnover figures and the list of major customers reflect our motto of manufacturing quality products.

After successfully establishing a market for proximity sensors through a nation-wide dealer’s network, Proximon has entered into the manufacturing of SMPS (Switch Mode Power Supplies). With the addition of this product, the company is poised to record overall sales growth of a minimum of 150% in the current year.

The quality control of Proximon products starts from basic raw material and continues right up to all stages of production, down to the finished product testing & even to final usage, where we extend services to our customer in the proper handling of Inductive Proximity Sensors and other related products.

We have steadily progressed over a strong infrastructural base, which enables us to be stable and grow higher to reach the peak of success. Our well equipped factory enables us to manufacture products in-house with much ease and precision; helping us fabricate the best for our clients.

Name of quality
The quality control of Proximon products starts from basic raw material and continue right upto all stages of production down to finished product testing & even to final usage of where we extend services to our customer in the proper handling of the product.

Testing of raw material

• All electronic components such as resistors, capacitors, transistors, diodes, zener diodes, voltage regulator IC's, SCR's, op-amps, special purpose Ics, etc are checked for acceptance and are shifted to production department for actual usage.
• As these components are required in huge quantity, the method of sampling inspection is adapted. The sampling plan is as follows :
• Metallic / plastic enclosures are tested and checked for physical dimensions such as diameter, pitch, length, and other parameters at the suppliers site. Necessary gauges & dies are developed by Proximon and kept at the vendors’ premises.
• Bare PCB’s are manufactured by M/s. Shogini Technoarts Pvt. Ltd., Pune as per our circuit diagram and PCB artwork. These PCB’s are subject to 100 % inspection for visual inspection such as track cracks, tinning, dimensions, shorting, etc. The track thickness is checked by thickness gauge. The track thickness should be minimum 8 microns.

To ensure minimum rejection at the final stage and best possible quality of product, inspection is carried out at various stages of manufacturing.

In-process Quality Control :
Temperature test : All components are inserted and soldered on PCB. After this, the populated PCB’s are checked for circuit working. The rejected populated PCB’s are sent, for reworking PCB’s are kept in laboratory oven @ 55oC for one hour and then tested for circuit working. The rejected PCB’s are scrapped. The accepted PCB’s are then sent for vibration test.

Vibration test : PCB’s are kept on vibration plate which vibrates at 50 Hz with 1 mm amplitude. This test help us to find out hidden dry solders and solder point cracks.

Electrical / other parameter testing : Sensing distance with respect to supply voltage, No load current, maximum output current, short circuit protection, reverse polarity protection, etc is tested. 100 % inspection is carried out for above mentioned tests. At this stage depending upon specific requirement of customer, certain tests are carried out ; e.g. in certain applications customer may be requiring 25 % hysterisis as against standard 10 %. Such instructions are included in the job sheet prepared by the marketing engineer.

Accepted PCB’s are then sent to the potting area where PCB’s are placed into the metallic/non-metallic housings. Depending upon the product potting is carried out These potted/unpotted products are then sent to final inspection stage and then to despatch department.

Finished good Inspection
Following tests are carried out in general. (Other tests are carried out depending upon specific requirement of customer).

• No load current
• Output current
• Voltage test
• Hysterisis
• Sensing distance variation
• Short circuit protection
• Reverse polarity protection
• Cable colour code
• Physical dimensions

Non confirming products are scraped immediately.

Accepted switches are then subjected to final heat run test. Here the switches are kept in ON condition for 3 hours, in OFF condition for 1 hour and again in ON condition for 3 hours.

The sampling plan is as follows :

• upto 50 nos. => 25% random samples => 2 nos. rejected => additional 25 %
• upto 100 nos. => 20 % random samples => 2 nos. rejected => additional => 20 %
• More than 100 nos => 15% random samples => 2 nos. rejected => additional 10%

To avoid any delay in delivery schedule, due to final stage inspection : usually 5% more than the order quantity is taken for processing.Note : Above mentioned tests, specifications varies with respect to the type of switch/product such as diameter, sensing distance, enclosure configuration, load technique, load logic, output load requirement, hysterisis, switching frequency etc.
