- White 80-case molded housing; 72-inch (6-foot) #22 AWG leads — for installations where the switch mounting location is far from the nearest wiring junction
$6.38Low Price Guarantee - $63.05SKU: 120RST-72-W
GRI 120RST-72-W Switch Set, 120RST-72-W with Leads
- GRI 120RST series: 3/4" switch, 3/8" magnet, press-to-fit recessed switch set with SPDT output; designed for wooden or aluminum door and window frames
- Requires a 3/4" hole for the switch and 3/8" hole for the magnet; the 3/4" switch mounting is desirable as extra wire and connections can be concealed in the larger hole, and testing or replacement is easily accomplished by pulling the switch and extending the extra wire to access connections
- SPDT output provides both normally open (N/O) and normally closed (N/C) contacts simultaneously — enabling flexible zone wiring for closed-loop, open-loop, or dual-circuit applications from one installed switch
$63.05Low Price Guarantee - $230.40SKU: 11536
GRI 11536 Water Sensor 2524-G 1-208-001
- GRI 2524 water sensor with relay contact; operates at 24V DC; normally open for an open loop circuit; detects any conductive non-flammable liquid; automatic reset; 6-foot jacketed lead standard; custom lead lengths available
- No mechanical parts: triggered by a moisture bridge across the sensor probe contacts; can be installed to detect a layer of water as minute as 1/16 of an inch in depth; relay output can be wired directly to any alarm panel or used to actuate an external device such as a transmitter or annunciator
- Open loop (2524) configuration: the relay contact output is normally open; when water is detected, the relay activates and the output closes — note that open-loop water sensors are not fail-safe, as loss of power to the sensor also results in loss of detection
$230.40Low Price Guarantee - $62.89SKU: 11535
GRI 11535 Switch Set, 4402AB with 2-5.6K Resistor
- GRI 4402-A industrial surface mount housing: weather-resistant rugged aluminum, 36-inch armored cable, SPDT configuration; suitable for chain link gates, overhead doors, safes, and walk-in freezer doors; mounting hardware included
- AB (biased for high security): the switch is biased into an opposite condition creating a double-tripping actuation window — a bypass magnet introduced at the center of this window causes the switch to release and alarm rather than stay silent
- Dual 5.6K ohm EOL resistors (series and parallel) factory-installed: provides full DEOL zone supervision for alarm panels requiring four-state zone monitoring (closed, alarm, open-circuit, and short-circuit) from a single field device
$62.89Low Price Guarantee - $73.20SKU: 11534-W
GRI 11534-W Potted Switch Set, X-VMDRR-Y, White
- White finish; factory-assembled X-VMDRR-Y configuration: a defined factory combination specifying the switch type, magnet, lead configuration, and encapsulation process for a specific OEM or application requirement
- Potting provides environmental protection beyond standard hermetic sealing of the reed element alone — the entire assembly, including leads and connections, is protected for use in wash-down, outdoor, coastal, refrigerated, or humid environments
- Ideal for food service, refrigeration, industrial, and exterior door applications where exposed connections would be subject to condensation, pressure washing, or chemical exposure
$73.20Low Price Guarantee - $46.02SKU: 11532
GRI 11532 Switch Set, 250-36HD with Shunt Loop
- GRI 250-series industrial wall mount switch set in the HD (heavy duty) variant: 18 AWG lead wire for higher current capacity compared to the standard 22 AWG version; 36-inch stainless steel armored cable
- Integrated shunt loop wiring configuration: provides panel-compatible zone supervision for wire integrity monitoring without an end-of-line resistor — the shunt loop creates a parallel path that keeps the zone circuit active even when the switch itself is in the normal (closed) state
- Extruded 6063 T5 aluminum housing tested to withstand a crushing force of 20,000 lbs (10 tons) without damaging the hermetically sealed reed switch; all mounting hardware including lead anchors and an actuating magnet bracket included
$46.02Low Price Guarantee - $46.85SKU: 11263-ZA
GRI 11263-ZA Switch Set, 4400-A Configuration 1B
- GRI 4400-A biased high-security industrial surface mount switch set; Configuration 1B single-biased arrangement; weather-resistant rugged aluminum housing; 36-inch armored cable
- 4400-A: 2-1/2" standard gap; closed loop; 10W, 200VDC, 0.50A; mounting hardware included; variety of optional mounting brackets available; ideal for chain link gates, overhead garage doors, safes, and walk-in freezer doors
- Biased Configuration 1B: creates a double-tripping window of operation; a secondary magnet introduced to defeat the switch causes an alarm rather than a bypass — eliminating the most common reed switch defeat technique
$46.85Low Price Guarantee - $50.96SKU: 11260-ZA
GRI 11260-ZA Switch Set, B250-36 Configuration 1B
- GRI B250-36 biased high-security wall mount switch set; industrial extruded aluminum 250-series housing; 36-inch armored cable; Configuration 1B single-biased arrangement
- Biased for high security: creates a double-tripping switch operable only within a specific window of operation defined by maximum and minimum actuation distances; a bypass magnet introduced at the center of this window causes the switch to release and alarm
- Configuration 1B: standard single-biased arrangement; for enhanced Configuration 4B biased protection, see the 11260-ZD
$50.96Low Price Guarantee - $47.81SKU: 11258-ZA
GRI 11258-ZA Switch Set, B200-36 Configuration 1B Biased
- GRI B200-36 biased high-security switch set: wall mount; industrial extruded aluminum housing; 36-inch armored cable lead; Configuration 1B single-biased arrangement; biased into the opposite condition of a standard reed to create a double-tripping switch
- The biasing operation creates a maximum and minimum actuation distance — a "window"; a bypass magnet introduced at the center of this window causes the switch to release and trigger an alarm, defeating the most common reed switch bypass attempt
- Configuration 1B: the standard single-biased configuration; provides the fundamental biased high-security function for applications requiring magnet defeat protection above standard closed-loop contacts
$47.81Low Price Guarantee - $110.16SKU: 11253-B-ZD
GRI 11253-B-ZD Switch Set, 28AXWG-B Configuration 4B
- Biased for high security: begins as a single pole double throw reed switch biased into an opposite condition — creating a double-tripping switch that can only be actuated inside a specific window of operation defined by a maximum and minimum actuation distance
- Configuration 4B: enhanced biased configuration providing a tighter actuation window and greater resistance to defeat by a secondary magnet compared to Configuration 1B — the higher the configuration number, generally the more difficult the magnet defeat attempt
- At approximately the center of the actuation window, should a compromising magnet be applied, it would be similar to moving the actuation magnet to the inside release limit, causing the switch to release and generate an alarm
