4AV20F-T1 Datasheet

Installation Instructions


Features, Applications

GENERAL INFORMATION 4AV Hall effect vane sensors include a Hall effect sensor and a magnet in a common package. They are operated by passing a ferrous vane through the gap between the magnet and the sensor. With no vane in the gap, the output is Operated (conducting). With the vane in the gap, the output is Released (non-conducting). The vane actuator is annealed low carbon cold rolled steel, type AISI 1018 or lower in carbon. Minimum recommended vane dimensions are required to ensure operating characteristics will be met.

DO NOT USE these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury. Failure to comply with these instructions could result in death or serious injury.

PRODUCT DAMAGE Do not exceed electrical specifications. Do not mis-wire the output connection. Do not reverse supply voltage polarity. Handle terminals with care. Failure to comply with these instructions may result in product damage.

PRODUCT DAMAGE Ensure iron tip is clean when soldering. Failure to comply with these instructions may result in product damage.

Hand Soldering The following is recommended: 1. Flux: Rosin Base 2. Solder: Kester #44 60-40 rosin core, or equivalent. 3. Soldering Iron: Type; Weller, Model TC-552, 55 watt or equivalent. 4. Tip Size: 3mm (.118 in.) Diameter 30mm (1.182 in.) long 5. Tip Temperature: 288�C (550�F) max 6. Terminal Contact Time: 6 seconds max. Wave Soldering The following is recommended: 1. Flux: London Chemical Co. Loncoflux 106A35 or equivalent 2. Preheat: Preheaters should be set to give �C (200 �F) on the top (component side) of printed circuit board just prior to board entering the wave. (May have to be adjusted depending upon board thickness.) 3. Solder Temperature: �C (500 �F) max.; preferably to 500 �F). 4. Speed: Set conveyor speed to approximately 4.5 feet/minute (1,37 meters/minute). 5. Printed circuit board requires rigid support during wave soldering.

Hand Cleaning Clean areas with a 50-50 mixture of isopropyl alcohol and clean tap water. Dry �C (160 �F) oven for 10-15 minutes, preferably in a noncirculating oven. This will remove all moisture from the assembly, which must be done before electrical testing, or application. Machine Cleaning * Detergent: London Chemical Company Loncoterge 444-NRT6 or equivalent. Equipment: Dee Electric Aqueous Cleaner or equivalent. The following is reccommended: 1. Wash Section: �C (130 �F) maximum water temperature, to 10% maximum solution soft water, low pressure nozzles (60 psi) on top spray and high pressure nozzles (120 psi) on bottom spray, conveyor speed 3 feet/minute minimum. Recirculating tank. 2. Rinse Section #1: Clean tap water to 25 grains hard, salt free (to minimize possibility of corrosion), unheated, non-recirculating, with high pressure nozzles (120 psi). 3. Rinse Section #2: Clean deionized water only, high pressure nozzles (120 psi), unheated and non-recirculating. 4. Air Knife Section: To remove excessive amounts of water. 5. Drying Section: 71�C (160 �F) drying for 10-15 minutes, preferably in a non-circulating conveyor oven.

* In this cleaning system, the detergent in the wash section removes the non-polar contaminants, the first rinse removes the detergent solution, and the deionized water rinse removes the polar contaminants. The air knife and dryer remove all the moisture from the assembly, which must be done before electrical testing or application.

PRODUCT DAMAGE Ensure cleaner does not come in contact with sensor If other cleaning methods are selected for removal of flux residue. Failure to comply with these instructions may result in product damage.
