Page 10: Device Description
Device description Device description The Safety Switch of the S20 series is an electro-mechanical switching device in a housing made of glass-fibre-reinforced and non-combustible plastic; the device satisfies protection rating IP 67. The standard design facilitates easy replacement. By means of the funnel-shaped insertion opening, the actuator self-centers, even if the door is slightly misadjusted. - Page 11 63000106 2NC + 1NO, 1 cable entry / M12 plug 24.2 14.2 30.8 30.8 Figure 3.1: Dimensions of S20-P3C1-M20-FH, S20-P1C1-M20-FH30 and S20- P4C1-M20-FH in mm 14.2 M12x1 30.8 Figure 3.2: Dimensions of S20-P4C1-M12-FH in mm (M12 plug dimensions) Leuze electronic Buy: www.ValinOnline.com | Phone 844-385-3099 | Email: CustomerService@valin.com...
