Omron D41G is a high-coded RFID guard lock safety door switch for gates, designed to prevent people from being trapped inside hazardous areas. Switch and actuator are fixed to each other by pairing, with more than 1,000 coding variations available. Actuators with an integrated door handle reduce guard design time, and with the emergency exit unit the switch can be unlocked from inside even when no power is supplied. The wide key hole tolerates misalignment caused by hinge deformation, and the auxiliary output notifies you when the actuator is not locked.
According to the datasheet, D41G is a Type 4 interlocking device to ISO 14119 with high coding. The interlocking function reaches PL e, Category 4 to ISO 13849-1 and is suitable for SIL3 applications; the guard lock function is PL d, Category 2. Holding force is 2,000 N min. and latching force 30 N. Two PNP safety outputs (OSSD) are rated 0.25 A and the auxiliary output 0.05 A; supply is 24 VDC. Up to 31 switches can be connected in series. Connection is via screw terminal (M20) or M12 connector, and protection is IP66 and IP67.
