What type of cable sγ‍&hould I use?
Electro-Sensors uses and recomme←‍☆nds a high-quality 22 AWG audiβ©∑↔o/instrument signal caλ∏™ble.

· For 2 conductor cable use a Belden 8÷ε761, or equivalent, shielded cable.

· For 3 conductor cable♦β♦ use a Belden 8771, or equivalent, sh¥$✔✔ielded cable.

· For 4 conductor cable use a Beld✔£∑←en 8723, or equivalent, shielded ca'✘α↔ble.

· For 6 conductor cable u↑>§se a Belden 9260, or equivalβ₹∏ent, shielded cable.

What are the standard cable ≠βlengths available from th€® e factory?
Sensors are available with 10, 5₩↓&0, 100, and multiples of©<$ 100 of cable.

How far can I run my sensor cab™‌ le wire?
The standard cable length on mos​¶t Electro-Sensors sensors is λ ×₩10 feet, however, our stand•¥÷ard Hall-Effect Sensors can be mounted∏•  up to 1500 feet away from  φone of our meters or modules whe​×φn using a quality cable.

What is each of the wires o< βn my sensor for?

Present in bi-directional ver₽∞™≤sions only

What type of Output does my>☆→ sensor give?
Electro-Sensors standard Hall-Ef♦§÷fect Sensors give a NPN Open C☆∑₽ollector, current sinking output.≤‌ The output is a digital squareβσ wave alternating from zer£​o to supply voltage. We also have optioβ♥™nal PNP Open Collector, c☆εurrent sourcing sensors.★£$↑

What value pull-up resistor should I us∏₹e with an Electro-Sensors sensor?
All Electro-Sensors products have an β₹→internal pull-up resisto¶☆ →r. However, if you are sending £∑×the pulses to a device witho₽¥σut one, you will need to supply ÷$←one. A suitable pull-up resistor can b∞δe anywhere from a 1 K-ohm - 3.3 K-↑₩£×ohms, however, be sure not to exceed£★≥ 25mA on the sensor. Additionally, ensu∞←​¥re the resistor is rated for 200% of th•≥∏¶e expected maximum w ✘attage it will dissipate &‍at 25°C. If using ¼ watt resi¶≠★stors good values are:

What is the maximum worki∞∞ng voltage and current my→"¥ sensor can handle?
Electro-Sensors Hall ‌•♦↑Effect sensors can work up to ÷↑ 24 Vdc at 25 mA maximum. λ₹&However, we strongly recommend an o♣ ♠perating current of less t£★✘han 20 mA.

Do I need a separate ε★δ≈DC power supply to power the Hall Ef•δfect Sensor?
When using the sensor with an Electro-φδ↕☆Sensors product (Speed Swit≤δ¶​ch, Tachometer, etc.) no separat®™e power supply is needed. Those produ¥☆‍®cts have a built in s↔αγupply to power the sensor. Ifλδ   not using with an Electro-Sensor©₩•s product, check the specificati&♠£ons of that product.

Can my sensor be used with an Intrinsi¶↑↓cally Safe Barrier?
Yes, Electro-Sensors Hall Effect, Magnσφetoresistive, and Digital Ring Kit π₩'♦Sensors meet the requir β♦♣ements of intrinsica✔<γβlly safe apparatus an★€δ​d associated apparatus for use≥® in Class I, II, and III; Division I✔÷₩ hazardous (classified) loca∑‍♦®tions. ANSI/UL 913-1988 - Catego§δry 16

How do I test my sensor to make sure≈ δ↑ it is working properly?

· Electro-Sensors analog s☆÷©≥ensors (Models 916, 917) can be teste×'<λd by disconnecting the sensor from th∑←<e electronics, and connectγ→×αing an ohmmeter to the black and cl®×≥ear wires. A properly working sen£ sor would have an ohm reading of a​≤≈₽pproximately 10,000 ohms.

· Electro-Sensors standar§®d Hall Effect Sensors (Models 906, 907,‍₽★  931, 932, 933, 1101, 1102, ★∏δ•1201, and 1202) require♥©£‍ an electrical test. Plσ>•‍ease contact the fact←φory for details.

Do I need a two or three piece s ∑↓haft monitoring system? 
Many applications are mδ'ore suited to having the switch electrφ©onics and sensor right at the ¥≤≈monitoring point (a two piece sys★>±‌tem) that way everything is calibrated♦£λ right there. Other applications★‌§ require the switch to be remo≈‌↓tely mounted from the sensor and disc ≥©(a three piece system). Space limita 'λtions, environmental consideration'¥€✔s, and personal preference all™£ play a part in determining the s•δ♣×peed switch system require≥♠♦d figure out what you need before  φγ≈installation begins it will→λα≥ save you time and money<∞​ in the long term.

What type of sensor do I nee‌≠™d for my application?
Electro-Sensors offers several differe≠∑↓≠nt types of sensor hou™λ♦☆sings to meet even the most demanding←₹¶ and diverse of applicati∏♦•on needs. Our standard aluminum body se☆★nsors will work in mo™€α st applications, but we also have ✘&&explosion proof sensors and the choi™↕ce of either stainle±↓©ss steel or PVC sensors for corro♥<÷&sive environments. Our explosion proof →εδsensors are also a great chδ±​oice for harsh environments su'γ  ch as rock quarries or mining ap£¥♥plications where a rugged h♥ε∞÷ousing is required to protect the se‌Ωnsing head. All of ou↕​§&r sensors can be suppl↑¶ied with high-temp Teflon cabl₽≠←¥e if required for higher temperature aק₹↔pplications.

What are my pulse ge↓↓♦nerating options?
Electro-Sensors offers a wide range of∞™₽× shaft end mount pulser discs and over≠'  shaft mount pulser wraps. Ifγ × the end of the shaft to be monit≠• ored is readily available, thenδ¶÷± in many cases, it makes sense to c↓≠£hoose a pulser disc toβ¥ generate pulses. If the shaft end is n♦<↓ot available, then you can use a pulserλ ↓ wrap this is a custo☆∏♠•m made pulse generator &¥Ωλthat is a split collar that clamps arou&•γσnd the shaft and installs in se₹‌&Ωconds. Over the years we hav≠÷e manufactured thousands of cu™¶stom pulser discs and wraps, a₽≈φnd either way weve go$ ‌<t you covered.
