Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
The 9104-12-42 from Coto Technology is the Form B version of the CotoClassic 9104 Series, a four-pin moulded SIP reed relay switching up to 1000V with a dielectric strength of 4000V minimum. It has a 12VDC coil and hermetically sealed contacts. Each relay is tested 100%, even at high voltage across all pin combinations.
In the 9104 Series, Form B contacts are available with a 12V coil and 4000V dielectric strength only, as the 9104-12-42. The Form B version does not have a magnetic shield. The optional coil suppression diode is available in the Form A configuration only.
Applications for the 9104 Series include automated test equipment, instrumentation, medical equipment, battery management, process control and solar systems. Switching voltage is 1000V maximum DC or peak AC into a resistive load. Switching current is 0.5A maximum and carry current 1.3A maximum, with a contact rating of 10W. Switching current is limited to 1.0mA at 1000V.
The coil is 12.0VDC nominal and 15.0VDC maximum, with a resistance of 500Ω ±10% at 25°C. The relay must operate by 9.0VDC and must release by 0.4VDC. Operate time including bounce is 1.0msec typical, measured at nominal coil voltage on a 30Hz square wave. Release time is 1.0msec typical.
Dielectric strength is 4000V minimum between contacts and 4000V minimum from contacts and shield to coil, measured as DC or peak AC. Insulation resistance is 10¹¹Ω minimum between all isolated pins, measured at 100V, 25°C and 40%RH. Static contact resistance is 0.150Ω maximum initial at 50mV and 10mA; dynamic contact resistance is 0.200Ω maximum initial at 0.5V and 50mA, measured at 100Hz over 1.5msec. Capacitance across open contacts is 1.0pF typical with no shield.
The operating temperature range is -20°C to +85°C and storage is -35°C to +100°C. Vibration is rated at 20G to 2000Hz and shock at 50G. Life expectancy is 50 × 10⁶ operations typical at a signal level of 1.0V and 10mA. Life expectancy at other switching loads is available from the factory.
The 9104-12-42 is a four-pin SIP for through-hole mounting, with pins 1 to 3 at 7.62mm, 3 to 5 at 5.08mm and 5 to 7 at 7.62mm. The body is 24.13mm long, 6.22mm wide and 8.13mm high at most. Relays are packed 18 to a tube.
All electrical parameters are measured at 25°C unless otherwise specified. Full specifications and configuration options are in the product datasheet.
