User manual 3M PROTECTING THE CIRCUITRY ON THE NARROW SENSOR CIRCUIT

[. . . ] Application Profile Market: Elevator Application Description: Protecting the circuitry on the narrow sensor circuit boards that span the length of the doors. Application Method By hand. PRODUCT 3MTM BumponTM Protective Product SJ-5003 Key Application Requirements Spacers must be able to protect the components from being crushed when subjected to pressure or impact. Benefits/Advantages To Customer Adhesive strength: Aggressive, high-tack, pressure-sensitive adhesive provides excellent performance on many kinds of surfaces. Application flexibility: Products are available in a variety of shapes and sizes; colored products are available as well as transparent. [. . . ] A protective cover fits over this thin circuit board (which allows the signal to transmit through it), though it could flex and come in contact with the components mounted on the circuit board and possibly damage them. To help avoid this problem, 3MTM BumponTM Protective Products are attached directly onto the circuit board. Since they have a higher profile than the components, only the Bumpon protector will be contacted if the cover is flexed. These circuit boards are also mounted in a position set back from the actual opening so they cannot be tampered with. · For spacer applications: 3MTM BumponTM Protective Products SJ-5003, SJ-5027, SJ-5012, SJ-5008, and SJ-5018. · For electronic equipment assembly applications: 3MTM BumponTM Protective Products SJ-5012, SJ-5023, SJ-5518, SJ-5523, SJ-5744, SJ-5003, SJ-5001, SJ-5302, SJ-5303, and SJ-5312. · Rollstock: 3MTM BumponTM Protective Products SJ-5816, SJ-5916, SJ-5808, SJ-5904, and SJ-6032.
