Features: Photoelectric Switch uses the blocking or reflection of the detected object to the beam, to detect the existence of the object. Photoelectric Switch converts the input current into a light signal on the transmitter, and the receiver detects the target object according to the strength or presence of the received light. Objects are not limited to metal, and all objects that reflect light (or block light) can be detected. It uses infrared light to detect objects without contact or damages. High precision, quick response, strong anti-interference capability. Specification: Detection Range: 70cm±10% Detection Range Adjustment: sensitivity regulator Detection Target: transparent/opaque object Response Time: 1ms On-delay: 1.5ms Light Source: infrared light 660nm Supply Voltage: DC12-24V(6-36V) impulse (P-P) <10% Withstand Voltage: AC1000V 50/60Hz 1min, between charging part and housing Voltage Influence: ±10% detection distance (within ±15% of rated supply voltage range) Current Consumption: N.P type: <20mA, A type: <1.7mA Control Output: N.P type: <300mA, A type: <400mA, J type: <2A Contact Life: 100,000 times Circuit Protection: N.P.D type: reverse connection protection, surge absorption, load short circuit protection; A type: surge absorption Operation Environment: -30~65°C (no freezing, no condensation), 35-95% RH Temperature Influence: temperature range -30~65°C, at +23°C: ±15% detection distance; temperature range: -25~60 ° C, at +23 ° C: ± 10% detection distance Insulation Impedance: >50MΩ (DC500 megohmmeter), between charging part and housing Housing Material: ABS Detection Surface (lens): PMMA Weight: 118g (approx.)
