Non-Contact Sensors

Differential-Hall-Effect Series A5S... 
Your first choice for permanent installation. Detecting small and large steel profiles (gear wheels, slots, holes). Outstanding performance under hard ambient conditions: Speed range 0... 12,000 pulses per sec, equally high and powerful output over  theentire range, adequate for transmission over more than 500 meters. Level approximay that of supply voltage. Profile size down to gear m 0,8 (pitch 32), slot or hole width down to 3 mm. Gap (clearance) to target nearly up to 4 mm. Their differential principle fights the influence of other magnetic fields and machine vibration. Sealed (>200 bar) stainless steel enclosure with smooth or threaded shaft 5/8UNF, or M12, M14, M18, or M22, length as option

Temperature -40°C ...+125°C ( -40 ... +255 °F). Connection via tight plug or firm cable.

Opto-electronic Sensor Series A1S...

Applicable to all objects, including plastic parts (fan blades, for instance). A  not profiled target (smooth shaft, for instance) will be easily marked  by a paint dot or by our adhesive reflective tape. Local environment should be kept clean. Signal conditioning in evaluation unit recommended, as provided by our C118, C156, or E1519 units.
Speed range 0/10 ...20,000 pulses per sec. Connection detachable with plug, or tight by firm cable. Signal transmission up to 10 meters (as standard), A1S40 up to 100 meters.   Specific application characteristics of A1S... series:

Model No.

Application Characteristics

A1S30... A1S36..

easy handling, the favourite for variable use. Scanning distance 1...2 cm (depending on reflection).Sensor shaft 8 mm ?, length 35 or 95 mm. Supply typically by evaluating unit.

A1S37P

Laser type reflection sensor with scanning distance up to 2 meters. Laser beam < 3 mm in ?, thereby sharp resolution. Requires marking with reflective tape U1A006.

A1S40

Infrared reflection sensor. Cylindrical enclosure with mounting thread M30. Scanning distance up to 50 cm. Optional fibre glass adapters for extreme conditions (temperature up to 300 °C, for instance).

Proximity Type sensor series A4S....

Applicable to larger sized profiles of steel or non-ferrous material. Allowing a large gap(clearance) between sensor and target: useful at a center displaced wheel, or if particles have to pass between sensor and target. Range from zero up to medium speed. Typical feeder belts, blades.  Characteristics vary widely between different models.

Magnetic pick-up sensor series A2S...

Detecting speed of rotating steel profiles, specifically at high speed, and under high temperature (turbines, turbo-blowers, for instance). Also, the alternating magnetic field around transformers, ignition coils, or rotating magnetic parts. Output signal varies with frequency and gap, therefore requiring high sensitivity of the receiver input, or a local pre-amplifier. 
Not for low speed applications.These sensors do not require supply. Various design models available.
