Why buy from Accent
Our own plant, not an import label
Proximity switches have been designed and built at our facility in Vikhroli, Mumbai, since 1985.
Kastl Electronic collaboration
A technical collaboration with Kastl Electronic GmbH, Germany, brought thick-film hybrid circuitry to Indian sensor manufacture for the first time.
Surface-mount before anyone else here
The first Indian company to build sensors on a surface-mount line, for smaller housings and repeatable quality.
Every unit, not a sample
Each switch is burn-in tested, with 100% in-process and post-production inspection and over 90% of joints machine-soldered.
Rated the way the standard defines it
Sn, Sa, hysteresis and repeat accuracy are specified to IEC 60947-5-2. ISO certified. See how we test.
What we make
Every switch below is designed and manufactured at our Mumbai plant to IEC 60947-5-2, and stocked for short domestic lead times. We supply aerospace, industrial automation, oil and gas, pharmaceutical, textile, cement and packaging plants across India.
Inductive range at a glance
DC 3-wire inductive proximity switches (D30C series). 10 to 30 V DC, reverse-polarity protected, IP67, −10 to +70 °C. Hysteresis ≤15% of Sn, repeat accuracy ≤10%, temperature drift ≤10% of Sn.

Sn and Sa as defined in IEC 60947-5-2: Sn is the rated figure, Sa is the distance at which operation is assured for any unit under any permitted condition. Also available as 2-wire DC, 2-wire AC (40 to 250 V AC), NAMUR and analog (0–5 V, 0–10 V, 4–20 mA, 0–20 mA). Nickel-plated brass housing, stainless steel on request.

Replacing an imported sensor?
Send us the part number you use today. We will reply with the Accent equivalent, its rated distance to IEC 60947-5-2, and a price, built and stocked in Mumbai rather than shipped in.
We regularly cross-reference Omron, Pepperl+Fuchs, Autonics, Telemecanique / OsiSense, ifm, Turck and Balluff part numbers.
