Part no.: M103
• ATEX/IECEx approved for mining
• Sensor Mounting: Flange or Body ClampsSpring loaded pushrod option available
• Available in any measurement range from 0-2mm to 0-50mm (for 51-100mm range see P133)
• Sealed to IP65/67 depending on connector/cable option
The intrinsically safe M103 is ATEX and IECEx approved for use in potentially explosive gas/vapour, dust atmospheres and mining environments. It is designed for a wide range of industrial applications and is ideal for OEMs seeking good sensor performance in situations where a short-bodied sensor is required for operation in hazardous areas. The unit is compact and space-efficient, being responsive along almost its entire length, and like all Positek sensors provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-2mm to 0-50mm and with full EMC protection built in.
Overall performance, repeatability and stability are outstanding over a wide temperature range.
The sensor has a rugged stainless steel body and plunger. It is easy to install and set up, mounting options include flange and body clamps. The plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. The M103 also offers a wide range of mechanical options, environmental sealing is to IP65 or IP67 depending on selected cable or connector options.
Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier . Approved galvanic isolation amplifiers (X005) are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.
The sensor can be installed with a cable length up to 1km between the sensor and the amplifier.

Miniature Kit Encoders Ensure High Performance in Maxon Micromotors
With the increasing sophistication of electronic controls for mechanical systems, there is more demand for durable, accurate and easy to use displacement sensors. As automation becomes more common there is also an increasing sensitivity to price. Customers also want sensors that can be easily connected and mechanically integrated.
Wiegand Effect Energy Harvesting
The “Wiegand effect” was discovered almost fifty years ago and has been used successfully in several specialized applications. However, its full potential for energy harvesting and signal generation has received only limited recognition. With recent enhancements to the energy output from Wiegand devices and the emergence of a new generation of ultra-efficient electronic chips for wireless communications, the technology is showing significant promise, especially in the exciting new area of the Internet of Things (IoT). UBITO, a member of the FRABA Group of technology companies, is leading research and development projects aimed at fulfilling this promise.
Inductosyn: End of an Era, New Opportunities or Both?
Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.
Technical Note: Intrinsically Safe vs. Inherently Safe Sensors
Intrinsically safe (IS) sensors are designed to operate safely in hazardous areas where there is a risk of explosion. IS sensors limit the amount of electrical and thermal energy that can be released in the event of a fault, to a level below that which is capable of igniting flammable gases, vapors, or dust.
