AHF22

AHF2 SMALL, HIGHLY RELIABLE TIP SENSOR CONTAINING A PHOTO SENSOR AHF2 (TIP) SWITCHES Compliance with RoHS Directive FEATURES Realizes miniaturization of equipment and spaces saving. Size of body: 9.5×9.5×9.3 mm The contact type is equivalent to normally closed contacts, which satisfies the PL Act. The internal sphere can be used over an operation angle of 360 degrees in the circumferential direction. There are three standard terminal profiles which can be selected according to the mounting direction of the PCB. The terminals are tin-plated for longterm solderability. TYPICAL APPLICATIONS Gas heaters Electric fans Water vallet Infrared treatment device Electric pots with warming function ORDERING INFORMATION Mounting direction Part No. Vertical mounting AHF21 Horizontal mounting AHF22 Reverse mounting AHF23 PCB mounting condition Remark: Standard Packaging: Tube 50 pcs. CONTACT TYPE Normally closed type (The photo transistor is ON when the sensor is being used.) APPLICABLE CIRCUIT Refer to the dimensional diagram for the terminal Nos. VCC = 5 V R2 = 100 kΩ Forward current, IF, of the LED: 19 mA (VCC = 5 V, R1 = 200 Ω) Forward voltage, VF, of the LED: Typ = 1.2 V Terminal No. 2 IF Terminal No. 1 R1 (VCC) VCC R2 Terminal No. 3 VO Tip switch Terminal No. 4 BASIC CHARACTERISTICS For Ta = 25°C and applicable circuit conditions 1) Operation characteristics (Operation speed 6 degrees/second) Operation angle (Output: VOL → VOH): 25 to 60...
