DATA SHEET Liquid Level Switch Optomax Digital LLC200D3SH-LLPK1 FEATURES Optomax Digital liquid level switches are ideal for applications with restricted space that require a miniature, low power and low cost sensing solution. The microcontroller based sensor is solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. Housing/ Output Type / Supply Output Temp Mounting Logic Voltage Current TECHNICAL SPECIFICATIONS OUTPUT VALUES 5 Supply voltage (Vs) 4.5V to 15.4V DC DC Output Voltage (Vout): lout = 100mA Supply current (ls) 2.5mA max. (Vs = 15.4V ) Output High Vout = Vs - 1V max DC Output sink and source Output Low Vout = 0V + 0.5V max current (lout) 100mA Operating temperatures -25C to +80C Other sensor options available on request, email: Storage temperatures -30C to +85C 1 technical sstsensing.com Housing material Polysulfone Sensor termination 24AWG, 250mm PTFE wires, 8mm tinned Need help Ask the expert 2 3 Tel: +44 (0)1236 459 020 Mounting thread M12x1x8g with hex nut 4 Operating pressure 7bar / 101psi maximum and ask for Technical Tightening torque 1.5Nm / 13.26 in-lb maximum 1) Before use check that the fluid in which you wish to use these devices is compatible with Polysulfone.
