SERIES 1056/1055/1058 - ENCLOSED SNAP ACTION SWITCHES PROTECTION TYPE IP 40 AND IP 67, UP TO 4 A 12 V / 2 A 24 V PRODUCT ADVANTAGES u Series 1055 / 1058: compact design with dust and water proof switching system according to IP 67, versions 1058 are also protected with IP 67 from the terminal side u Large over-travel, 1.2 mm despite small size u Small operating point tolerances u The special actuator design enables an approach angle up to 40 u Switching reliability by tension spring contact system u For electrical ratings up to 4 A 12 V resp. 2 A 24 V u The modular principle offers a wide selection of terminals, optional actua- tors and types of fastenings SWITCHING FUNCTION SERIES 1055/1056 u Change-over SWITCHING FUNCTIONS SERIES 1058 u Change-over u Normally open u Normally closed TERMINAL VERSIONS u Solder terminal u Straight PCB terminal u Angled PCB terminal u Bent PCB terminal, asymmetrical con- nections u Quick-connect terminal u Top side connection wires (only 1058) VERSIONS ON REQUEST u With electrical rating 0,5 (0,5) A 250 V~ 25E3 and ENEC- approval mark u For ambient temperature > 100 C u Different optional actuators u Other connection wires and different lengths 3.640 Electrical rating 4 A 12 V 2 A 24 V Actuating force series 1055/1058 1,8 N series 1056 1,3 N Mechanical life endurance 1E6 Electrical life endurance 10 mA / 12 V 1E6 2 A / 12 V 200E3 Contact resistance (new state) < 50 m Insulation resistance (new state) > 100 M (500 V DC between the open contacts) Protection type series 1056 actuating side IP 40 terminal side IP 00 Protection type series 1055 actuating side IP 67 terminal side IP 00 Protection type series 1058 actuating side IP 67 terminal side IP 67 Contact gap < 3 mm () Ambient temperature -40 C ... +85 C no condensation Storage temperature -40 C ... +100 C Flammability UL 94 V-2 Material socket / housing / actuator PA / PBTP / POM optional actuator (1055 and 1058) chrome-nickel steel Contacts AuAg plated Connection slits tinned Solderability of terminals max. 350 C, 2-3 sec. (without pressure on the terminals when soldering by hand ) Approval mark on request APPROACH ANGLE UP TO 40 The robust actuator guide allows actua- tion by slide or camshaft from all direc- tions with an approach angle 40. The mechanical life depends on the material and surface properties of the slide and the insatallation situation in the device. The diagram opposite is also applicable to the 1056 and 1058 series. 3.7
