Available with a built-in LED. What is a force guided relay? Relays used in safety circuits to detect failures such as contact welding and damage to the contact spring. Contacts of a force guided relay are forced to open and close by a guide connected to the armature. Due to requirements of standard EN50205, a force guided relay has independent NO and NC contacts. If a NO contact welds, a NC contact will not close even when the relay coil is turned off (de-energized) and must maintain a gap of at least 0.5 mm. Furthermore, if a NC contact welds, a NO contact will not close when the relay is turned on (energized) and must maintain a gap of at least 0.5 mm. (General-purpose relays do not have the above characteristics.) De-energized (Normal Condition) De-energized (Abnormal Condition) NO contact NC contact NO contact is welded Guide Armature A gap of at least 0.5 mm is maintained Energized (Normal Condition) Energized (Abnormal Condition) NO contact NC contact A gap of at least 0.5 mm is maintained Guide Armature NC contact is welded NC contact Guide NO contact Applications Force guided relays are used in safety circuits in combination with interlock switches, light curtains, and emergency stop switches to control outputs. They can also be used to expand outputs for safety relay modules and safety controllers.

Driving Circuit for Relays 1. To make sure of correct relay operation, apply rated voltage to the relay coil. Pickup and dropout voltages may differ according to operating temperature and conditions. 2. Input voltage for DC coil: A complete DC voltage is best for the coil power to make sure of stable operation. When using a power supply containing a ripple voltage, suppress the ripple factor within 5%. When power is supplied through a rectifications circuit, relay operating characteristics, such as pickup voltage and dropout voltage, depend on the ripple factor. Connect a smoothing capacitor for better operating characteristics as shown below. 5. Surge suppression for transistor driving circuits: When the relay coil is turned off, a high-voltage pulse is generated. Be sure to connect a diode to suppress the counter electromotive force, or use RF1V with counter-electromotive force diode. Then, the coil release time becomes slightly longer. To shorten the coil release time, connect a Zener diode between the collector and emitter of the controlling transistor. Select a Zener diode with a Zener voltage slightly higher than the power voltage. 3. Usage, transport, and storage conditions 1. Temperature, humidity, atmospheric pressure during usage, transport, and storage. Temperature: -40C to +85C (no freezing) See page 4 for the current and operating temperature. Humidity: 5 to 85%RH (no condensation) The humidity range varies with temperature. Use within the range indicated in the chart below. Atmospheric pressure: 86 to 106 kPa Operating temperature and humidity range Counter emf suppressing diode + - R Relay Humidity (%RH) 85 Smoothing Capacitor + - Tolerance Range R Relay Pulsation 6. The coil terminal of the relay has polarity. Connect terminals according to the internal connection diagram. Incorrect wiring may cause malfunction. (Avoid freezing when using at temperatures below 0C) 2. Protection for Relay Contacts TE R Load EAC Vin EAC Vin If the relay operates in sync with AC power voltage of the load, the relay life may be reduced. If this is the case, select a relay in consideration of the required reliability for the load. Or, make the relay turn on and off irrespective of the AC power phase or near the point where the AC phase crosses zero voltage. 4. Leakage current while relay is off: When driving an element at the same time as the relay operation, special consideration is needed for the circuit design. As shown in the incorrect circuit below, leakage current (Io) flows through the relay coil while the relay is off. Leakage current causes coil release failure or adversely affects the vibration resistance and shock resistance. Design a circuit as shown in the correct example. Incorrect TE R R + Power D - Power Varistor 3.

Load This protection circuit is very effective in arc suppression when opening the contacts. But, when the contacts are closed, a current flows to charge the capacitor, causing contact welding. R C Power C Power Generally, switching a DC inductive load is more difficult than switching a DC resistive load. Using an appropriate arc suppressor will improve the switching characteristics of a DC inductive load. 5. Others 1. General notice To maintain the initial characteristics, do not drop or shock the relay. The relay cover cannot be removed from the base during normal operation. To maintain the initial characteristics, do not remove the relay cover. Use the relay in environments free from condensation, dust, sulfur dioxide (SO2), and hydrogen sulfide (H2S). The RF1V relay cannot be washed as it is not a sealed type. Also make sure that flux does not leak to the PC board and enter the relay. 2. Connecting outputs to electronic circuits: When the output is connected to a load which responds very quickly, such as an electronic circuit, contact bouncing causes incorrect operation of the load. Take the following measures into consideration. Connect an integration circuit. Suppress the pulse voltage due to bouncing within the noise margin of the load. 3. Do not use relays in the vicinity of strong magnetic field, as this may affect relay operation. 4. UL and CSA ratings may differ from product rated values determined by IDEC. 7 RF1V Force Guided Relays/SF1V Relay Sockets Operating Instructions 6. Notes on PC Board Mounting * When mounting 2 or more relays on a PC board, keep a minimum spacing of 10 mm in each direction. If used without spacing of 10 mm, rated current and operating temperature differs. Consult IDEC. * Manual soldering: Solder the terminals at 400C within 3 sec. * Auto-soldering: Preliminary heating at 120C within 120 sec. Solder at 260C5C within 6 sec. * Because the terminal part is filled with epoxy resin, do not excessively solder or bend the terminal. Otherwise, air tightness will degrade. * Avoid the soldering iron from touching the relay cover or the epoxy filled terminal part. * Use a non-corrosive resin flux.
